Moduli of surface diffeomorphisms with cubic tangencies
Shinobu Hashimoto
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 condit…

Moduli of 3-dimensional diffeomorphisms with saddle-foci
Shinobu Hashimoto, Shin Kiriki, Teruhiko Soma
We consider a space of 3-dimensional diffeomorphisms with hyperbolic fixed points the stable and unstable manifolds of which have quadratic tangencies and sat…
