Partially hyperbolic geodesic flow via conformal deformation
Ygor de Jesus, Luis Pedro Piñeyrúa, Sergio Romaña
This paper presents a new construction of non-Anosov Partially Hyperbolic Geodesic flows. Our construction is closely related to the construction made by Carneiro and Pujals, the n…

Rigidity of Lyapunov Exponents for Geodesic Flows
Nestor Nina Zarate, Sergio Romaña
In this paper, we study rigidity problems between Lyapunov exponents along periodic orbits and geometric structures. More specifically, we prove that for a surface M without focal…

Entropy of Singular Suspensions
Elias Rego, Sergio Romaña
In this work, we investigate diffeomorphisms whose positiveness of topological entropy is destroyed by singular suspensions. We show that this phenomenon is rare in the set of $C^1…
