Explosion of differentiability for equivalencies between Anosov flows on 3-manifolds
Mario Bessa, Sergio Dias, Alberto A. Pinto
For Anosov flows obtained by suspensions of Anosov diffeomorphisms on surfaces, we show the following type of rigidity result: if a topological conjugacy between them is differenti…
Positive Lyapunov exponents for symplectic cocycles
Mario Bessa, Paulo Varandas
In the present paper we give a positive answer to a question posed by Viana on the existence of positive Lyapunov exponents for symplectic cocycles. Actually, we prove that for an…
A dichotomy in area-preserving reversible maps
Mario Bessa, Alexandre Rodrigues
In this paper we study R-reversible area-preserving maps f on a two-dimensional Riemannian closed manifold M, i.e. diffeomorphisms f such that Ro f=f^{-1}o R where R is an isometri…
Generic area-preserving reversible diffeomorphisms
Mário Bessa, Maria Carvalho, Alexandre Rodrigues
Let M be a surface and R an involution in M whose set of fixed points is a submanifold with dimension 1 and such that R is an isometry. We will show that there is a residual subset…
