Topological mixing in CAT(-1) metric spaces
Ch. Charitos, G. Tsapogas
If X is a proper CAT(-1)-space and a non-elementary discrete group of isometries acting properly discontinuously on X, it is shown that the geodesic flow on the quotient space…

Approximation of recurrence in negatively curved metric spaces
Ch. Charitos, G. Tsapogas
For metric spaces with curvature less than or equal to x, x<0, it is shown that a recurrent geodesic can be approximated by closed geodesics. A counter example is provided for the…
