Abstract

In this paper, we study spherically symmetric Finsler metrics F=|y|f(|x|,\frac{}{|y|}), where x \in Bn(r) \subset Rn, y \in TxBn(r)\{0} and f:[0,r)\times R \rightarrow R. By investigating a PDE equivalent to these metrics being locally projectively flat, we manufacture projectively flat spherically symmetric Finsler metrics in terms of error functions and, using Shen's result, we give its flag curvature.

By investigating a PDE equivalent to these metrics being locally projectively flat, we manufacture projectively flat spherically symmetric Finsler metrics in terms of error functions and, using Shen's result, we give its flag curvature.
