Popis: | In this paper, we investigate the existence of parallel 1-forms on specific Finsler manifolds. We demonstrate that Landsberg manifolds admitting a parallel 1-form have a mean Berwald curvature of rank at most $n-2$. As a result, Landsberg surfaces with parallel 1-forms are necessarily Berwaldian. We further establish that the metrizability freedom of the geodesic spray for Landsberg metrics with parallel 1-forms is at least $2$. We figure out that some special Finsler metrics do not admit a parallel 1-form. Specifically, no parallel 1-form is admitted for any Finsler metrics of non-vanishing scalar curvature, among them the projectively flat metrics with non-vanishing scalar curvature. Furthermore, neither the general Berwald's metric nor the non-Riemannian spherically symmetric metrics admit a parallel 1-form. Consequently, we observe that certain $(\alpha,\beta)$-metrics and generalized $(\alpha,\beta)$-metrics do not admit parallel 1-forms. Comment: 16 pages |
