Renormalization of vector fields, and applications to invariant tori and reducibility problems
Complexo Interdisciplinar, Sala B3-01

Sasa Kocic (Universidade de Texas, Austin)

Abstract:

I will describe the construction of renormalization schemes for vector fields on T^d \times R^m and skew product flows on T^d \times SL (2,R). I will also discuss the applications of these schemes to the construction of invariant tori in near-integrable systems in the former case, and to reducibility of skew product flows in the latter case.
