Katok-Hasselblatt-kinematic expansive flows
Huynh Minh Hien
In this paper we introduce a new notion of expansive flows, which is the combination of expansivity in the sense of Katok and Hasselblatt and kinematic expansivity, named KH-kinema…

A solution to Flinn's conjecture on weakly expansive flows
Huynh Minh Hien
In L.W. Flinn's PhD thesis published in 1972, the author conjectured that weakly expansive flows are also expansive flows. In this paper we use the horocycle flow on compact Rieman…

Expansiveness for the geodesic and horocycle flows on compact Riemann surfaces of constant negative curvature
Huynh Minh Hien
We study expansive properties for the geodesic and horocycle flows on compact Riemann surfaces of constant negative curvature. It is well-known that the geodesic flow is expansive…
