On CW-translations of homogeneous Finsler spaces with (?,?)-metrics
(Balkan Society of Geometers, 2021-03-01T00:00:00) Rani, S.; Shanker, G.
In the present paper, we consider homogeneous Finsler spaces with two (?,?)-metrics. Taking a Killing vector ?eld X on one of these spaces, we find necessary and su?cient conditions for X to be Killing on the other space. Further, by taking a Killing vector ?eld X of constant length on one of these spaces, we ?nd the condition under which the Killing vector ?led X has constant length w.r.t. other space also. Taking Killing vector ?elds of constant length, we ?nd CW translations on these spaces. � 2021 Balkan Society of Geometers, Geometry Balkan Press. All Rights Reserved.
On the rigidity of spherically symmetric Finsler metrics with isotropic E-curvature
(Balkan Society of Geometers, 2021-01-01T00:00:00) Rani, S.; Shanker, G.
In the current paper, first we establish the formula for mean Berwald curvature of a spherically symmetric Finsler metric. Further, we establish differential equations characterizing projectively flat as well as dually flat spherically symmetric Finsler metrics. Finally, we obtain a rigidity result on spherically symmetric Finsler metrics with isotropic E-curvature. � Balkan Society of Geometers, Geometry Balkan Press 2021.
