PrerequisiteUndergraduate general topology and complex analysis.AbstractIn this course, we give a panorama of geometric structures a topological surface can be endowed with. We will discuss combinatorial decompositions, natural dynamical systems and moduli spaces of these structures. We will focus on geometric structures compatible with a structure of Riemann surface (translation structures, di...
AbstractThis course is an introduction to geometric numerical integration for ordinary differential equations based on the theory of dynamical systems. The course will cover the following topics:1) Brief introduction to basics of dynamical systems;2) K. Feng’s idea on geometric numerical integration;3) Symplectic integration methods for Hamiltonian systems;4) Backward error theory of geometric...
