projectively related einstein finsler spaces

the main objective of this paper is to find the necessary and sufficient condition of a given finslermetric to be einstein in order to classify the einstein finsler metrics on a compact manifold. the consideredeinstein finsler metric in the study describes all different kinds of einstein metrics which are pointwiseprojective to the given one. this study has resulted in the following theorem tha...

On the Projectively Extended Linear Spaces

In this article, we show that a linear space whose parameters are those of the complement of a subset in a finite projective plane π of order n such that no line is removed and a sufficient number of lines lost only one point, is projectively extended linear space.

On Projectively Related Einstein Metrics

In this paper we study pointwise projectively related Einstein metrics (having the same geodesics as point sets). We show that pointwise projectively related Einstein metrics satisfy a simple equation along geodesics. In particular, we show that if two pointwise projectively related Einstein metrics are complete with negative Einstein constants , then one is a multiple of another.
