Computation of Normal Forms

4:00 PM-6:00 PM
Plumeria & Tiare (Salon 9 & 10)

Normal form theory plays an important role in the study of dynamical systems. The basic idea of normal form is to apply successive coordinate transformations to a given differential equation so that the resulting equation has a simpler form. Recently, more attention has been paid to the simplest normal forms, and some new computation methods have been developed. The purpose of this minisymposium is to exchange the new ideas in the direction of computation of simplest normal forms.
