Moduli of surface diffeomorphisms with cubic tangencies
arXiv:1804.08400 · doi:10.3836/tjm/1502179278
Abstract
In this paper, we study conjugacy invariants for 2-dimensional diffeomorphisms with homoclinic cubic tangencies (two-sided tangencies of the lowest order) under certain open conditions. Ordinary arguments used in past studies of conjugacy invariants associated with one-sided tangencies do not work in the two-sided case. We present a new method which is applicable to the two-sided case.
