A variational principle for impulsive semiflows
Jose F. Alves, Maria Carvalho, Carlos Vasquez
We consider impulsive semiflows defined on compact metric spaces and deduce a variational principle. In particular, we generalize the classical notion of topological entropy to our…
Invariant probability measures and non-wandering sets for impulsive semiflows
Jose F. Alves, Maria Carvalho
We consider impulsive dynamical systems defined on compact metric spaces and their respective impulsive semiflows. We establish sufficient conditions for the existence of probabili…
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…
