Short course on
Compact Riemann surfaces and the KdV equation
by Ian McIntosh (University of York)
Waseda University
September 2020
real time Zoom lectures*
Dr Ian McIntosh(University of York)
This series of lectures will be an introduction to compact Riemann surfaces, with a view towards applications to integrable systems such as the KdV equation.The author is a renowned specialist in this area and an excellent speaker. The only prerequisites are first course in complex analysis and calculus of several variables.
Each lecture will include ample time for discussion and questions. Graduate students and researchers in mathematics, physics, and engineering are welcome (see below for registration information).
