Math 497C - Honors MASS Geometry
An introduction to geometric topology in dynamics
Instructor: Federico Rodriguez-Hertz, Professor of Mathematics
TA: Kurt Vinhage
MWRF 1:25 - 2:15 p.m.
Description: The objective of the course is to build geometric tools that enables to give an accurate description of a dynamical system. We will start with circle diffeomorphisms and covering maps and their classification through topological invariants like rotation number and degree. Then we shall move to surface diffeomorphisms (particularly when the surface is the torus) and give some consequence of their homotopy type. In the mean time we shall introduce the notion of fundamental group, covering space, homotopy invariants, conjugacy invariants, suspension of a diffeomorphism, foliations, flows on surfaces.
Readings: The main reference we will use is the book “Introduction to the Modern Theory of Dynamical Systems” B. Hasselblatt and A. Katok, Cambridge University Press . We shall use some input from the books: A. Casson and S. Bleiler, “Automorphisms of Surfaces After Nielsen and Thurston”, Cambridge Univ. Press; A. Hatcher, “Algebraic topology” http://www.math.cornell.edu/~hatcher/#ATI; and/or “J. Milnor Topology from the “Differentiable Viewpoint”, Princeton University Press; and/or V. Guillemin and A. Pollack. “Differential Toplogy” Prentice Hall
