Abstract: |
In this paper, we study a new class of general $(\alpha,\beta)$-metrics $F$ defined by a Riemannian metric $\alpha$, a 1-form $\beta$ and ${\mathcal {C}}^{\infty}$ function $\phi(b^{2},s)$. We provide the projective factor of a class of general $(\alpha,\beta)$-metrics $F=\alpha\phi(b^{2},s)$, and apply these formulae to compute its flag curvature. |
