Séminaire scientifique à l'I2M présenté par Kemo Morvan, conférence mathématique destinée aux chercheurs et étudiants
Kemo Morvan: In this talk, we are interested in the group Aut(X,0) of automorphisms of the germ (X,0) of a complex analytic space. We show that Aut(X,0) contains a contracting automorphism if and only if the singularity (X,0) is quasi-homogeneous. This extends previous results by Favre and Ruggiero for the normal surface case, as well as the recent results by Ornea and Verbitsky for the isolated s
