The neutrino pair annihilation ( $ν ν ˉ ⟶ e^{-} e^{+}$ )around a massive source with an $f (R)$ global monopole

Yuxuan Shi, Hongbo Cheng

In this work we investigate the neutrino pair annihilation around a gravitational object involving an $f (R)$ global monopole. We derive and calculate the ratio $\frac{\dot{Q}}{\dot…

The characterizations on a class of weakly weighted Einstein-Finsler metrics

Xinyue Cheng, Hong Cheng, Pengsheng Wu

In this paper, we study the weakly weighted Einstein-Finsler metrics. First, we show that weakly weighted Einstein-Kropina metrics must be of isotropic S-curvature with respect to…
