2. Distinguished Women in Mathematics Colloquium, Friday, March 11, 2022, 15:30

The Department of Mathematics and Statistics at the University of Ottawa
is proud to host Prof. Christiane Rousseau (Montreal) for the annual
Distinguished Women in Mathematics Colloquium.
The colloquium takes place on Friday March 11 at 3:45 PM.
You are all invited to join the presentation online (information below).

Title: The equivalence problem in analytical dynamics

Abstract: A central problem in local dynamics is the equivalence
problem: when are two analytic systems locally equivalent under an analytic coordinate change?  In the neighborhood of a singular point, the representatives of the equivalence classes could be given by normal forms. But, most often, the coordinate changes to the normal form diverge. Why does this happen? What does this mean? The unfolding of singularities reveals geometric obstructions to convergence to the normal form.

In this talk, we discuss a class of singularities and their unfoldings for which we can provide moduli spaces for equivalence problems. We explain the common geometric features of these singularities, and how the study of the unfolding of these singularities allows us to understand both the singularities themselves, and the obstructions to the existence of analytic coordinate changes to the normal form.

You are invited to a Zoom meeting.

When: Mar 11, 2022 15:30 Eastern Time (US and Canada)
