Terrà un seminario dal
titolo:
“Iterated
monodromy groups for Henon maps”
Abstract:
In this talk I relate several combinatorial descriptions for the Julia
sets of hyperbolic polynomial diffeomorphisms of C^2: external angles by
E.Bedford and J.Smillie, automata by R.Oliva and Hubbard trees by myself.
Iterated monodromy groups, originally introduced for partial self-coverings of
arcwise connected spaces, are defined for such polynomial diffeomorphisms and
are used to construct automata from Hubbard
trees.
Tutti gli
interessati sono invitati a partecipare.
