Título: "(Arc)-connectedness of the space of Z^d actions on 1-manifolds"

Expositor: Andrés Navas (Universidad de Santiago de Chile)

Resumen:
 
We will elaborate on two recent results obtained in collaboration with Hélène
Eynard-Bontemps (Inst. Fourier, Grenoble): - The space of Z^d actions by
C^{1+ac} diffeomorphisms of a compact 1-manifold is path-connected; - The space
of Z^d actions by C^2 diffeomorphisms of the interval is connected. Here, "ac"
stands for absolutely continuous. I will deeply comment on several technical
problems when dealing with these properties: Mather's homomorphisms, failure of
Sternberg's linearization theorem, etc. Several questions will be addressed
along the talk.
