Some curvature properties of Cartan spaces with mth root metrics
Preprint
Abstract
In this paper, we prove that every m-th root metric with isotropic mean Berwald curvature reduces to a weakly Berwald metric. Then we show that an m-th root metric with isotropic mean Landsberg curvature is a weakly Landsberg metric. We find necessary and sufficient condition under which conformal $\beta$-change of an m-th root metric be locally dually flat. Finally, we prove that the conformal $\beta$-change of locally projectively flat m-th root metrics are locally Minkowskian.Keywords
