Abstract We Survey the Published Work of Harry Kesten in Probability Theory, with Emphasis on His Contributions to Random Walks
Abstract We survey the published work of Harry Kesten in probability theory, with emphasis on his contributions to random walks, branching processes, perco- lation, and related topics. Keywords Probability, random walk, branching process, random matrix, diffusion limited aggregation, percolation. Mathematics Subject Classification (2010) 60-03, 60G50, 60J80, 60B20, 60K35, 82B20. Noname manuscript No. 2(will be inserted by the editor) Geoffrey R. Grimmett Harry Kesten's work in probability theory Geoffrey R. Grimmett In memory of Harry Kesten, inspiring colleague, valued friend April 8, 2020 1 Overview Harry Kesten was a prominent mathematician and personality in a golden period of probability theory from 1956 to 2018. At the time of Harry's move from the Netherlands to the USA in 1956, as a graduate student aged 24, much of the foundational infrastructure of probability was in place. The central characters of probability had long been identified (including random walk, Brownian motion, the branching process, and the Poisson process), and connections had been made and developed between `pure theory' and cognate areas ranging from physics to finance. In the half-century or so since 1956, a coordinated and refined theory has been developed, and probability has been recognised as a crossroads discipline in mathematical science. Few mathematicians have contributed as much during this period as Harry Kesten. Following a turbulent childhood (see [59]), Harry studied mathematics with David van Dantzig and Jan Hemelrijk in Amsterdam, where in 1955 he attended a lecture by Mark Kac entitled \Some probabilistic aspects of potential theory". This encounter appears to have had a decisive effect, in that Harry moved in 1956 to Cornell University to work with Kac. -
Game Dynamics Karl Sigmund University of Vienna, Austria
The Center for Control, Dynamical Systems, and Computation University of California at Santa Barbara Winter 2007 Seminar Series Presents Game Dynamics Karl Sigmund University of Vienna, Austria Tuesday, February 13th, 2007 2:00pm-4:00pm ESB 1001 Abstract: Game dynamics can be viewed as a combination of game theory and ecology, with applications in many other fields. In this talk, the role of heteroclinic attractors (consisting of saddle points and saddle connections) will be highlighted. In usual dynamical systems, such attractors are not robust, but they often occur (in the form of Rock-Paper-Scissors cycles) in strategic interactions. This talk deals with examples, basic results and open problems. About the Speaker: Karl Sigmund attended school in the lycée francais de Vienne. From 1963 to 1968, he studied at the Institute of Mathematics at the University of Vienna, and obtained his Ph.D. under the supervision of Leopold Schmetterer. He then spent the following postdoc years in Manchester (68-69), the Institut des Hautes Etudes in Bures sur Yvette near Paris (69-70), the Hebrew University in Jerusalem (1970- 71), the University of Vienna (1971-72) and the Austrian Academy of Science (1972-73). In 1973 Karl was appointed C3-professor at the University of Göttingen, and in 1974 full professor at the Institute of Mathematics in Vienna. His main scientific interest during these years was in ergodic theory and dynamical systems. From 1977 on, Karl became increasingly interested in different fields of biomathematics, and collaborated with Peter Schuster and Josef Hofbauer on mathematical ecology, chemical kinetics and population genetics, but especially on the new field of evolutionary game dynamics and replicator equations. -
Faculty Document 2436 Madison 7 October 2013
University of Wisconsin Faculty Document 2436 Madison 7 October 2013 MEMORIAL RESOLUTION OF THE FACULTY OF THE UNIVERSITY OF WISCONSIN-MADISON ON THE DEATH OF PROFESSOR EMERITA MARY ELLEN RUDIN Mary Ellen Rudin, Hilldale professor emerita of mathematics, died peacefully at home in Madison on March 18, 2013. Mary Ellen was born in Hillsboro, Texas, on December 7, 1924. She spent most of her pre-college years in Leakey, another small Texas town. In 1941, she went off to college at the University of Texas in Austin, and she met the noted topologist R.L. Moore on her first day on campus, since he was assisting in advising incoming students. He recognized her talent immediately and steered her into the math program, which she successfully completed in 1944, and she then went directly into graduate school at Austin, receiving her PhD under Moore’s supervision in 1949. After teaching at Duke University and the University of Rochester, she joined the faculty of the University of Wisconsin-Madison as a lecturer in 1959 when her husband Walter came here. Walter Rudin died on May 20, 2010. Mary Ellen became a full professor in 1971 and professor emerita in 1991. She also held two named chairs: she was appointed Grace Chisholm Young Professor in 1981 and Hilldale Professor in 1988. She received numerous honors throughout her career. She was a fellow of the American Academy of Arts and Sciences and was a member of the Hungarian Academy of Sciences, and she received honorary doctor of science degrees from the University of North Carolina, the University of the South, Kenyon College, and Cedar Crest College. -
Hans Thirring, on the Formal Analogy Between the Basic Electromagnetic Equations and Einstein’S Gravity Equations in first Approximation
Gen Relativ Gravit (2012) 44:3217–3224 DOI 10.1007/s10714-012-1450-4 GOLDEN OLDIE EDITORIAL Editorial note to: Hans Thirring, On the formal analogy between the basic electromagnetic equations and Einstein’s gravity equations in first approximation Herbert Pfister Published online: 26 October 2012 © Springer Science+Business Media, LLC 2012 Keywords Gravitomagnetism · Frame dragging · Lense–Thirring effect · Experimental relativity · Golden Oldie 1 Technical comments on the Thirring paper The paper contains some inconsistencies and errors, and an undefined quantity, which, however, does not invalidate the final equations for gravitomagnetism. Since in a realistic rotating body (angular velocity ω) there arise centrifugal stresses of order ω2, it is inconsistent to incorporate the velocities v of the field-generating body up to second order but to treat this body as incoherent matter (dust). The same incon- sistency appeared in Thirring’s model of a rotating mass shell [1], which therefore did not correctly solve the Einstein equations (in the shell). For this case the inconsistency was observed and corrected by Lanczos [2]. In the present paper the inconsistency has no severe consequences because the second order terms in v anyhow are quite unimportant. An error in Thirring’s paper appears in the integration volume dV0 which has to be substituted by dV = dV0/(dx4/ds). The same error appeared in Thirring’s paper [1] on the rotating mass shell, was there observed by M. Laue and W. Pauli, and corrected by Thirring in [3]. But, as with the inconsistency with the incoherent The republication of the original paper can be found in this issue following the editorial note and online via doi:10.1007/s10714-012-1451-3. -

Real Proofs of Complex Theorems (And Vice Versa)
REAL PROOFS OF COMPLEX THEOREMS (AND VICE VERSA) LAWRENCE ZALCMAN Introduction. It has become fashionable recently to argue that real and complex variables should be taught together as a unified curriculum in analysis. Now this is hardly a novel idea, as a quick perusal of Whittaker and Watson's Course of Modern Analysis or either Littlewood's or Titchmarsh's Theory of Functions (not to mention any number of cours d'analyse of the nineteenth or twentieth century) will indicate. And, while some persuasive arguments can be advanced in favor of this approach, it is by no means obvious that the advantages outweigh the disadvantages or, for that matter, that a unified treatment offers any substantial benefit to the student. What is obvious is that the two subjects do interact, and interact substantially, often in a surprising fashion. These points of tangency present an instructor the opportunity to pose (and answer) natural and important questions on basic material by applying real analysis to complex function theory, and vice versa. This article is devoted to several such applications. My own experience in teaching suggests that the subject matter discussed below is particularly well-suited for presentation in a year-long first graduate course in complex analysis. While most of this material is (perhaps by definition) well known to the experts, it is not, unfortunately, a part of the common culture of professional mathematicians. In fact, several of the examples arose in response to questions from friends and colleagues. The mathematics involved is too pretty to be the private preserve of specialists. -

Exhibition: the Vienna Circle - Exact Thinking in Demented Times
! ! Exhibition: The Vienna Circle - Exact Thinking In Demented Times. As part of the 650 year anniversary of the University of Vienna, the exhibition „The Vienna Circle“ will be displayed at the University’s main building from May 20th, 2015 until October 31st, 2015. The Vienna Circle, a group of outstanding thinkers, played an important part in Philosophy and science in the 1920’s and 1930’s: The group’s discussions and philosophical approaches set the cornerstones for important developments in a multitude of fields of science. On Tuesday, May 19th, at 5:00pm the exhibition will be opened by the rector of the University Vienna Heinz W. Engl. Other distinguished speakers include major Michael Häupl, the president of the Austrian Academy of Science Anton Zeilinger, Nobel Prize Winner Martin Karplus as well as Media Artist Peter Weibel. The exhibition was curated by Karl Sigmund and Friedrich Stadler. After leaving Vienna, the exhibition will be displayed in Karlsruhe. „Today, the Vienna Circle would be considered an internationally influential science Think Tank. Its members stood for the free development of science, scientific and rational analysis in politics and culture as well as the modernization of the society they lived in. The achievements of the members of the Vienna Circle still have impact on today’s science and research areas: the discussions of the Vienna Circle eventually led to innovations like the basics of mathematical logic as well as theoretical computer science“, says Heinz W. Engl, rector of the University of Vienna. The objects and documents mostly focus on the philosophical questions the Vienna Circle discussed: How can the efficiency of mathematics be explained? What is the role of logical propositions? What is the basis of scientific knowledge? The greatest challenge for the curators was to „visualize philosophy“: making the abstract, philosophical work of the Vienna Circle accessible to and understandable for a broad audience.
