Update concerning Covid-19 pandemic

Published on Dec. 14, 2020, [View only this article]

After a summer, in which at least some hybrid activities welcoming visitors on-site could take place, the ESI is closed again since the beginning of October. Nevertheless, thanks to the efforts of some organizers, some online activities could be offered. We very much hope we will be able to have on-site events soon, but currently it is unclear when that will happen. We will continue to monitor the situation closely and post any changes on the ESI webpage. With best wishes for the Holiday Season,

First ESI-Medal goes to Anton Alekseev

Published on June 23, 2020, [View only this article]

The Medal of the Erwin Schrödinger Institute for Mathematics and Physics for the year 2020 is awarded to Anton Alekseev from the University of Geneva.

Prof. Alekseev is honoured for his recent outstanding contributions to mathematics, in particular for the discovery of the link between the Grothendieck-Teichmüller group and the long-standing Kashiwara-Vergne problem in Lie theory, for the program of tropicalization of Poisson structures, and for the proof of the Goldman-Turaev formality in 2-dimensional topology. His work unites brilliant intuition, deep knowledge, and remarkable technical skills.

The award ceremony will take place on September 24, 2020 at the Erwin Schrödinger Institute.

Anton Alekseev

Anton Alekseev studied at the Leningrad State University and was trained at the Steklov Mathematical Institute in St. Petersburg where he obtained his PhD in Mathematical Physics in 1991. After research positions in Zurich and Uppsala, he became full professor for mathematics at the University of Geneva in 2001.

Alekseev has worked on a wide range of topics in mathematical physics and pure mathematics including algebra and geometry, as well as mechanics and field theory. He has made seminal contributions in these disciplines, and often his work uncovers connections and unexpected links between them.

His works on the Kashiwara-Vergne conjecture on the structure of the Baker-Campbell-Hausdorff formula in Lie theory are groundbreaking. With E. Meinreken he obtained a proof in 2006, in further works with C. Torossian and others he uncovered surprising relations of this algebraic problem to the theory of Drinfeld associators and later also to the topology of 2-dimensional surfaces.

The Medal of the Erwin Schrödinger Institute for Mathematics and Physics

The Medal of the Erwin Schrödinger International Institute for Mathematics and Physics, or ESI-Medal, awarded in 2020 for the first time, has been created to recognize outstanding achievements in any area of mathematics or physics, including contributions at the interface of the two fields.

The ESI-Medal is awarded annually and emphasis is generally given to recent achievements not older than ten years. There is no age limitation for the recipient and ordinarily the ESI-Medal is awarded to one person.

The recipient of the ESI-Medal receives a medal, a certificate and a monetary award of 4,000 Euro.

Nominations for the ESI-Medal can be made by organizers of ESI Thematic Programmes taking place in the year following the nomination deadline, former members of the Scientific Advisory Board (SAB) of the ESI, former recipients of the ESI-Medal, former Directors of the ESI and the President of the ESI Association. The recipient is selected by the Scientific Advisory Board of the ESI.

Wittgenstein-Award for ESI Kollegium Member Adrian Constantin

Published on June 22, 2020, [View only this article]

ESI-Kollegium Member Adrian Constantin has received the Wittgenstein-Award 2020 of the Austrian Science Foundation (FWF), the most prestigious science award in Austria. Adrian Constantin is a world leader in the theory and the application of nonlinear partial differential equations. Two of his articles are among the 10 most cited papers ever to be published by the journals in which they appear, which, in turn, rank among the most prestigious journals in all of mathematics: Acta Mathematica and Inventiones Mathematicae. Moreover, Adrian Constantin is listed as an ISI Highly Cited Researcher with more than 160 publications and 11000 citations.

The research of Adrian and his collaborators includes seminal contributions to fluid mechanics and geophysics, e.g. the proof of existence of rotational traveling water waves of large amplitude (with W. Strauss) and rigorous qualitative studies of wind-driven ocean currents. Adrian has developed and established novel analytical techniques that help unravel notoriously difficult wave phenomena in the oceans and in the atmosphere.

We congratulate Adrian on the Wittgenstein-Award 2020!

Erwin Schrödinger Lecture, Dec 6, 2018: Monika Henzinger (U Vienna) "Dynamic Graph Algorithms: A Survey"

Published on Feb. 26, 2019, [View only this article]

On December 6, 2018 at 5 p.m. the ESI is going to host an Erwin Schrödinger Lecture, featuring Monika Henzinger, a professor of Computer Science at the University of Vienna and a former director of research at Google. She received a PhD from Princeton University in 1993 and subsequently held positions at Cornell University, Digital Equipment Corporation, the University of the Saarland and the École Polytechnique Fédérale in Lausanne. Monika Henzinger is the recipient of numerous grants and awards including an NSF Career Award, an honorary doctorate from the Technical University of Dortmund, as well as an ERC Advanced Grant. In her research, she focuses on combinatorial algorithms and data structure and their applications.

As usual, this Erwin Schroedinger Lecture is directed towards a general audience of mathematicians and physicists. In particular it is an intention of theses lectures to inform non-specalists and graduate students about recent developments and results in some area of mathematics or physics.

Abstract: Real-world graphs are huge and many of them change dynamically. Thus to compute properties of these graphs we need dynamic graph algorithms that efficiently maintain properties of dynamically changing graphs. We present the state-of-the-art in dynamic graph algorithms and explain some of the techniques that they use as well as recent progress in giving lower bounds for their running time.
