Internationally renowned physicist first in lecture series

The first installment in the SUNYIT President's Lecture Series will feature internationally renowned physicist Pavel Winternitz of the Université de Montréal on Friday, September 14, at noon, in Donovan Hall Rm. G152.

Pavel WinternitzWinternitz grew up in Prague, was educated in St. Petersburg and Dubna, trained in the U.K and worked for a few years in the U.S. before settling permanently in Montreal in 1972. Since 1984 he has been full professor at the Université de Montréal. He held visiting appointments in France, Italy, Spain, Australia and Mexico.

Professor Winternitz is an internationally recognized researcher in mathematical physics, more specifically in the area of Lie groups and their applications. He contributed fundamentally to the theories of exactly solvable systems and of symmetries and integrability of difference equations. His name is a part of the scientific vocabulary, and some models of superintegrable potentials bear his name (Smorodinsky-Winternitz type). He is one of the most cited physicists of Czech origin, and his papers are among five of the most cited papers in the Journal of Physics A; one of his recent papers received the Best Paper prize in 2011 from the Journal of Mathemathical Physics. He was awarded the title Doctor Honoris Causa by the Czech Technical University in Prague and is a recipient of the prestigious prize "Ceska Hlava" (Czech Head), as well as the CAP-CRM Prize in Theoretical and Mathematical Physics. He was elected a Foreign Member of the Mexican Academy of Sciences.

He holds the following degrees:  Ph.D. in Theoretical Physics, Joint Institute for Nuclear Research, Dubna, Russia; M.Sc. in Theoretical Physics, University of Leningrad, (now St. Petersburg), Russia.

The September 14 lecture is entitled: 

Symmetries of difference equations and symmetry preserving discretization of differential equations

"We show how one can approximate an Ordinary Differential Equation by a Difference System that has the same Lie point symmetry group as the original ODE. Such a discretization has many advantages over standard discretizations. In particular it provides numerical solutions that are qualitatively better, specially in the neighborhood of singularities."
