Finsleroid-Finsler Space of Involutive Case

Abstract

The Finsleroid-Finsler space is constructed over an underlying Riemannian space by the help of a scalar $g(x)$ and an input 1-form $b$ of unit length. Explicit form of the entailed tensors, as well as the respective spray coefficients, is evaluated. The involutive case means the framework in which the characteristic scalar $g(x)$ may vary in the direction assigned by $b$, such that $dg=\mu b$ with a scalar $\mu (x)$. We show by required calculation that the involutive case realizes through the $A$-special relation the picture that instead of the Landsberg condition ${\dot{A}}_{ijk}=0$ we have the vanishing $\dot{\al}_{ijk}=0$ with the normalized tensor $\al_{ijk}=A_{ijk}/||A||$. Under the involutive condition, the derivative tensor $A_{i|j}$ and the curvature tensor $R^i{}_k$ have explicitly been found, assuming the input 1-form $b$ be parallel. Key words: Finsler metrics, spray coefficients, curvature tensors.
