The University of Arizona: Analysis, Dynamics, and Applications Seminar – The Symplectic Structure for Renormalization of Circle Diffeomorphisms with Breaks
February 20, 2024 @ 12:30 pm - 1:30 pm
Presenter: Konstantin Khanin, Department of Mathematics, University of Toronto, Canada
In the first part of the talk I’ll present the main results of the renormalization theory for circle homeomophisms. We then shall discuss the symplectic structure related to renormalisation of circle maps with breaks. The invariant symplectic form which we construct is related to the symplectic form introduced by Goldman back in 1984. This part of the talk is based on a joint paper with Selim Ghazouani.
