Abstract

In this paper, we classify up to isometry the connected and simply connected Riemannian nilmanifolds on six-dimensional filiform Lie groups and we compute the corresponding isometry groups. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we introduce two classes of stretch Finsler metrics. A Finsler metric with vanishing stretch B-curvature (stretch H-curvature) is called B-stretch (H-stretch) metric (respectively). The class of B-stretch (H-stretch) metric contain the class of Berwald (weakly Berwald) metric (respectively). First, we show that every complete B-stretch metric (H-stretch metric) is a B-metric (H-metric). Then we prove that every compact Finsler manifold with non-negative (non-positive) relatively isotropic stretch B-curvature (stretch H-curvature) is B-metric (H-metric). [ABSTRACT FROM AUTHOR]
