September 12 – 24, 2017 / Paul Wiegmann / University of Chicago, Department of Physics / [ Website ]
Professor / Theoretical Physics, Condensed Matter Physics

Paul B. Wiegmann is a Russian physicist. He is the Robert W. Reneker Distinguished Service Professor in the Department of Physics at the University of Chicago, James Franck Institute and Enrico Fermi Institute. He specializes in theoretical condensed matter physics. He made pioneering contributions to the field of quantum integrable systems. He found exact solutions of O(3) Non-linear Sigma Model, (Wiegmann 1985), Wess–Zumino–Witten model (together with Alexander Polyakov), Anderson impurity model and Kondo model. (WikipediA)

September , 2017 / Nikita Nekrasov / Simons Center for Geometry and Physics / [ Website ]
Professor /

Nikita Nekrasov is a mathematical physicist and string theorist at Stony Brook University in New York. Professor of the Russian Academy of Sciences.
Nekrasov studied at the Moscow State 57th School in 1986–1989. He graduated with honors from Moscow Institute of Physics and Technology in 1995, and joined the theory division of the Institute for Theoretical and Experimental Physics. In parallel, in 1994–1996 Nekrasov did his graduate work at Princeton University, under the supervision of David Gross. His PhD thesis on Four Dimensional Holomorphic Theories was defended in 1996.
In 2013, he moved to the Simons Center for Geometry and Physics at Stony Brook University as a full professor.

Seminars :

Professor / Analysis, Algebra, Applied Mathematics

Seminar :
“Geometric analysis of the discrete Painlevé equations”

May 21 – June 9, 2017 / Andrei Negut / MIT, Dep. of Mathematics / [ Website ]
Assistant Professor of Mathematics / Algebraic Geometry, Representation Theory

Andrei Negut’s overall program concentrates on problems in geometric representation theory, an area that overlaps studies in algebraic geometry and representation theory. His results connect to areas in mathematical physics, symplectic geometry, combinatorics and probability theory. His current research focuses on moduli of sheaves, quiver varieties, quantum algebras and knot invariants. Negut received the PhD from Columbia University in 2015, studying under Andrei Okounkov. He completed the Master’s in mathematics from Harvard in 2012, and the B.A. from Princeton in 2009

Seminar :
“W-algebras for surfaces”

May 10 – 24, 2017 / Dennis Gaitsgory / Harward Univ., Dep. of Mathematics / [ Website ]

Dennis Gaitsgory is a professor of mathematics at Harvard University known for his research on the geometric Langlands program. His work in geometric Langlands culminated in a joint 2002 paper with Edward Frenkel and Kari Vilonen, On the geometric Langlands conjecture establishing the conjecture for finite fields, and a separate 2004 paper, On a vanishing conjecture appearing in the geometric Langlands correspondence, generalizing the proof to include the field of complex numbers as well.

April 3 – 7, 2017 / Nikolay Gromov / King’s College London, Dep. of Mathematics / [ Website ] /

Nikolay Gromov joined King’s College as a Lecturer in Theoretical Physics in 2010, and was promoted to Reader in 2014.
Nikolay’s research interests include different approaches in non-perturbative Yang-Mills theory. The first approach is devoted to confinement/deconfinement phase transition and is based on classical configurations, generalizing the instantons. Another approach is based on the remarkable duality between the N = 4 super-symmetric generalization of 4D Yang-Mills theory and 10D string theory in the AdS5 x S5 background. Integrability allows one to write down the equations describing exactly the spectrum of these theories and easily reproduce very complicated perturbation theory calculations.

Seminar :
“Integrability in AdS/CFT without supersymmetry”
