In this paper, we prove that a non-Riemannian isotropic Berwald metric or a non-Riemannian (α,β) -metric admits no concurrent vector fields. We also prove that an L-reducible Finsler metric admitting a concurrent vector field reduces to a Landsberg metric.In this paper, we prove that a non-Riemannian isotropic Berwald metric or a non-Riemannian (α,β) -metric admits no concurrent vector fi...

in this paper, we study a class of finsler metrics which contains the class of p-reducible andgeneral relatively isotropic landsberg metrics, as special cases. we prove that on a compact finsler manifold,this class of metrics is nothing other than randers metrics. finally, we study this class of finsler metrics withscalar flag curvature and find a condition under which these metrics reduce to r...

Abstract The aim of the manuscript is to present concept a graphical double controlled metric-like space (for short, GDCML-space). structure an open ball proposed also discussed, and newly presented ideas are explained with new technique by depicting appropriately directed graphs. Moreover, we some examples in graph prove that our results sharp compared those previous papers. Further, existence...

Ricci-like solitons with arbitrary potential are introduced and studied on Sasaki-like almost contact B-metric manifolds. A manifold of this type can be considered as an complex Riemannian which cone is a holomorphic manifold. The soliton under study characterized proved that its Ricci tensor equal to the vertical component both B-metrics multiplied by constant. Thus, scalar curvatures respect ...
