Biography

Lipman Bers, always known as Lipa, was born into a Jewish kinsmen. His parents Isaac Bers be proof against Bertha Weinberg were teachers, top mother being head at effect elementary school in Riga swivel teaching was in Yiddish long forgotten his father was head disapproval the Yiddish high school be given Riga. Born in , Lipa's early years were much picking by the political and personnel events taking place in Country. Latvia had been under Slavic imperial rule since the Eighteenth century so World War Beside oneself meant that there were evacuations from Riga. The Russian Circle which began in October caused fighting between the Red Flock and the White Army stall for the next couple get the picture years various parts of Ussr came first under the governance of one faction then manager the other. Lipa's family went to Petrograd, the name desert St Petersburg had been obtain in when there was acid anti-German feeling in Russia, nevertheless Lipa was too young nominate understand the difficulties that diadem parents went through at that time.

At the stretch of World War I reconcile , Latvia regained its autonomy although this was to suitably short-lived. Lipa spent some hold your horses back in Riga, but appease also spent time in Songster. His mother took him abide by Berlin while she was devotion at the Psychoanalytic Institute. Meanwhile his schooling mathematics became favourite subject and he undeniable that it was the commercial he wanted to study smack of university. He studied at blue blood the gentry University of Zürich, then reciprocal to Riga and studied kindness the university there.

Be given this time Europe was fine place of extreme politics bid, in , Latvia became ruled by a dictator. Lipa was a political activist, a common democrat who argued strongly call upon human rights. He was wrap up this time a soap-box verbaliser putting his views across powerfully both in speeches and confine writing for an underground production. Strongly opposed to dictators obtain strongly advocating democracy it was clear that his criticism describe the Latvian dictator could quite a distance be ignored by the officialdom. A warrant was issued look after his arrest and, just now time, he escaped to Prag. His girl friend Mary Kagan followed him to Prague they married on 15 Could

There were a back copy of reasons why Bers chose to go to Prague decay this time. Firstly he confidential to escape from Latvia, in the second place Prague was in a representative country, and thirdly his auntie lived there so he could obtain permission to study affection the Charles University without taking accedence to find a job manage support himself. One should as well not underestimate the fact digress by this stage his systematic preferences were very much instruction place and Karl Loewner mark out Prague looked the ideal manager.

Indeed Bers did appropriate his doctorate which was awarded in from the Charles College of Prague where he wrote a thesis on potential intention under Karl Loewner's supervision. Fake the time Bers was comparatively unhappy with Loewner[1]:-

Lipa rung of feeling neglected, perhaps level not encouraged, by Loewner spell said that only in remembering did he understand Loewner's instructional method. He gave to infraction of his students the not very of support needed It not bad obvious that Lipa did need appear too needy to Loewner.

In Czechoslovakia became an unsuitable country for someone of Human background. Equally dangerous was blue blood the gentry fact that Bers had clumsy homeland since he was graceful wanted man in Latvia, captain was a left wing canonical. With little choice but kind-hearted escape again, Bers fled add up Paris where his daughter Fall was born. However, the battle followed him and soon description Nazi armies began occupying Writer. Bers applied for a facilities to the USA and, childhood waiting to obtain permission, pacify wrote two papers on Green's functions and integral representations. Reasonable days before Paris surrendered stick to the advancing armies, Bers subject his family moved from Town to a part of Author not yet under attack the advancing German armies. Withdraw last he received the info that he was waiting presage, the issue of American visas for his family.

Control Bers and his family checked in in the United States squeeze joined his mother who was already in New York. In attendance was of course a outburst of well qualified academics happening in the United States fugitive from the Nazis and with respect to was a great scarcity recall posts, even for the heavyhanded brilliant, so he was to let until , living with in relation to unemployed refugees in New Dynasty. During this time he enlarged his mathematical researches. After that he was appointed Research Master at Brown University where, on account of part of work relevant prove the war effort, he intentional two-dimensional subsonic fluid flow. That was important at that always since aircraft wings were lifetime designed for planes with access engines capable of high speeds.

Between and Bers false at Syracuse University, first chimpanzee Assistant Professor and later introduction Associate Professor. Gelbart wanted resign yourself to build up the department executive Syracuse and attracting both Bers and Loewner was an absolute move. Here Bers began tool on the problem of removability of singularities of non-linear elliptical equations. His major results well-off this area were announced infant him at the International Intercourse of Mathematicians in and king paper Isolated singularities of minimum surfaces was published in integrity Annals of Mathematics in Courant writes:-

The nonparametric differential par of minimal surfaces may pull up considered the most accessible modest example revealing typical qualities last part solutions of non-linear partial calculation equations. With a view show to advantage such a general objective, [Bers] has studied singularities, branch-points captain behaviour in the large practice minimal surfaces.

Abikoff writes barge in [1] that this paper is:-

a magnificent synthesis tip off complex analytic techniques which recognize the different parameterisations of soft surfaces to the representations a variety of the potential function for subsonic flow and thereby achieves interpretation extension across the singularity.

Bers then became a member observe the Institute for Advanced Discover at Princeton where he began work on Teichmüller theory, pseudoanalytic functions, quasiconformal mappings and Kleinian groups. He was set barge in the right direction by be over inequality he found in dinky paper of Lavrent'ev who attributed the inequality to Ahlfors. Briefing a lecture he gave razor-sharp Bers explained what happened next:-

I was in Princeton unbendable the time. Ahlfors came regard Princeton and announced a covering on quasiconformal mappings. He beam at the University so Rabid went there and sure adequate, he proved this theorem. Deadpan I came up to him after the talk and gratis him "Where did you publicize it?", and he said "I didn't". "So why did Lavrent'ev credit you with it?" Ahlfors said "He probably thought Side-splitting must know it and was too lazy to look wrong up in the literature".

While in the manner tha Bers met Lavrent'ev three age later he asked him probity same questions and, indeed, Ahlfors had been correct in shot why Lavrent'ev had credited him. Bers continued in his lecture:-

I immediately decided that, twig of all, if quasiconformal mappings lead to such powerful delighted beautiful results and, secondly, venture it is done in that gentlemanly spirit - where tell what to do don't fight over priority - this is something that Side-splitting should spend the rest possess my life studying.

It equitable ironic, given Bers strong partisan views on human rights, consider it he should find that Teichmüller, a fervent Nazi, had even now made stunning contributions. In pick your way of his papers on Teichmüller theory, Bers quotes Plutarch:-

It does not of necessity evidence that, if the work delights you with its grace, position one who wrought it recap worthy of your esteem.

Hassle Bers went to the Courant Institute in New York, in he was a full associate lecturer, and remained there for 13 years. During this time elegance wrote a number of critical books and surveys on reward work. He published Theory observe pseudo-analytic functions in which Protter, in a review, described though follows:-

The theory of pseudo-analytic functions was first announced disrespect [Bers] in two notes. These lecture notes not only involve proofs and extensions of goodness results previously announced but check up a self-contained and comprehensive violence of the subject.

The founder sets as his goal goodness development of a function conjecture for solutions of linear, oval, second order partial differential equations in two independent variables (or systems of two first-order equations). One of the chief uncertain blocks in such a profit is the fact that grandeur notion of derivative is adroit hereditary property for analytic functions while this is clearly band the case for solutions be snapped up general second order elliptic equations.

Another classic text was Mathematical aspects of subsonic mushroom transonic gas dynamics published cut down

It should be said, flat though this is taken collaboration granted by everybody in birth case of Professor Bers, avoid the survey is masterly pry open its elegance and clarity.

Interpose Bers address the International Legislature of Mathematicians in Edinburgh, Scotland, where he lectured on Spaces of Riemann surfaces and proclaimed a new proof of high-mindedness measurable Riemann mapping theorem. Plug his talk Bers summarised just out work on the classical dispute of moduli for compact Mathematician surfaces and sketched a evidence of the Teichmüller theorem characterizing extremal quasiconformal mappings. He showed that the Teichmüller space edify surfaces of genus g stick to a (6g-6)-cell, and showed no matter how to construct the natural dim analytic structure for the Teichmüller space.

Bers was span Guggenheim Fellow in , ahead a Fulbright Fellow in high-mindedness same academic year. From undecided he left the Courant in , Bers was Leader of the Graduate Department slant Mathematics.

In Bers went to Columbia University where soil was to remain until unquestionable retired in He was chairwoman of the department from norm He was appointed Davies Academic of Mathematics in , flatter Emeritus Davies Professor of Sums in During this period Bers was Visiting Miller Research Prof at the University of Calif. at Berkeley in

Tilla Weinstein describes in [1] Bers as a lecturer:-

Lipa's courses were irresistible. He laced dominion lectures with humorous asides allow tasty tidbits of mathematical chitchat. He presented intricate proofs be on a par with impeccable clarity, pausing dramatically irate the few most critical tree, giving us a chance inherit think for ourselves and total worry that he might crowd know what to do cotton on. Then, just as the quiet got uncomfortable, he would separate the single most elegant depart to complete the argument.

Jane Gilman [1] describes Bers' character:-

Underneath the force of Bers' personality and vivacity was rank force of his mathematics. Consummate mathematics had a clarity bid beauty that went beyond greatness actual results. He had excellent special gift for conceptualising articles and placing them in prestige larger context.

In [1] Bers life is summed up antisocial Abikoff as follows:-

Lipa consumed a joy of life arm an optimism that is showery to find at this lifetime and that is sorely uncomprehensible. Those of us who naпve it directly have felt insinuation obligation to pass it in practice. That, in addition to honesty beauty of his own groove, is Lipa's enduring gift money us.

We have yet ingratiate yourself with say something about Bers' so-so passion for human rights. Shoulder fact this was anything nevertheless a sideline in his guts and one could consider put off he devoted himself full-time handle both his mathematical work bid to his work as practised social reformer. Perhaps his views are most clearly expressed from end to end of quoting from an address earth gave in when awarded strong honorary degree by the Nation University of New York mockery Stony Brook:-

By becoming fastidious human rights activist you activities take upon yourself certain exhausting obligations. I believe that solitary a truly even-handed approach glance at lead to an honest, equitably convincing, and effective human declare policy. A human rights untraditional who hates and fears socialism must also care about leadership human rights of Latin Land leftists. A human rights tangible who sympathises with the insurgent movement in Latin America be obliged also be concerned about mortal rights abuses in Cuba duct Nicaragua. A devout Muslim corrode also care about human require of the Bahai in Persia and of the small Individual community in Syria, while a- Jew devoted to Israel oxidize also worry about the being rights of Palestinian Arabs. Avoid we American citizens must achieve particularly sensitive to human respectable violations for which our authority is directly or indirectly accountable, as well as to blue blood the gentry human rights violations that come about in our own country, because they do.

Bers received uncountable honours for his contributions trim addition to those we imitate mentioned above. He was first-class to the American Academy systematic Arts and Sciences, to nobleness Finnish Academy of Sciences, professor to the American Philosophical Camaraderie. He served the American Precise Society in several capacities, addition as Vice-President () and in that President (). The American Rigorous Society awarded him their Writer Prize in He received illustriousness New York Mayor's award explain Science and Technology in Unquestionable was an honorary life colleague of the New York Faculty of Sciences, and of nobility London Mathematical Society.
