Twelve characterisations of Killing vector fields in Finsler geometry

Ioan Bucataru, Georgeta Cretu, Luciana Daniliuc

It is well known that infinitesimal isometries preserve many of the canonical geometric structures of a Riemannian or Finslerian manifold. In this paper, we identify those geometri…

Strong Hamel functions and symmetries

Ioan Bucataru, Georgeta Cretu

For the geodesic spray of a Finsler space, a strong Hamel function is a Hamel function that is the geodesic derivative of a -homogeneous potential function. Similarly, strong du…

Finsler metrizabilities and geodesic invariance

Ioan Bucataru, Oana Constantinescu

We prove that various Finsler metrizability problems for sprays can be reformulated in terms of the geodesic invariance of two tensors (metric and angular). We show that gyroscopic…

First integrals for Finsler metrics with vanishing -curvature

Ioan Bucataru, Oana Constantinescu, Georgeta Cretu

We prove that in a Finsler manifold with vanishing -curvature (in particular with constant flag curvature) some non-Riemannian geometric structures are geodesically invariant an…

Invariant volume forms and first integrals for geodesically equivalent Finsler metrics

Ioan Bucataru

Two geodesically (projectively) equivalent Finsler metrics determine a set of invariant volume forms on the projective sphere bundle. Their proportionality factors are geodesically…

A class of Finsler metrics admitting first integrals

Ioan Bucataru, Oana Constantinescu, Georgeta Cretu

We use two non-Riemannian curvature tensors, the -curvature and the mean Berwald curvature to characterise a class of Finsler metrics admitting first integrals.
