A Finsler metric of constant Gauss curvature on 2-sphere

I. Masca, S. V. Sabau, H. Shimada

We construct a concrete example of constant Gauss curvature on the 2-sphere having all geodesics closed and of same length.

Finslerian indicatrices as algebraic curves and surfaces

P. Chansri, P. Chansangiam, S. V. Sabau

We show how to construct new Finsler metrics, in two and three dimensions, whose indicatrices are pedal curves or pedal surfaces of some other curves or surfaces. These Finsler met…

Surfaces of revolution admitting strongly convex slope metrics

P. Chansagiam, P. Chansri, S. V. Sabau

This paper discusses the geometry of a surface endowed with a slope metric. We obtain necessary and sufficient conditions for any surface of revolution to admit a strongly convex s…

The geometry of a Randers rotational surface with an arbitrary direction wind

Rattanasak Hama, Sorin V. Sabau

In the present paper we study the global behaviour of geodesics on a Randers metric, defined on a topological cylinder, obtained as the solution of the Zermelo's navigation problem…

The geometry on the slope of a mountain

P. Chansri, P. Chansangiam, S. V. Sabau

The geometry on a slope of a mountain is the geometry of a Finsler metric, called here the {\it slope metric}. We study the existence of globally defined slope metrics on surfaces…

On the existence of convex functions on Finsler manifolds

Sorin V. Sabau, Pattrawut Chansangiam

We show that a non-compact (forward) complete Finsler manifold whose Holmes- Thompson volume is infinite admits no non-trivial convex functions. We apply this result to some Finsle…
