A Novel Method for Calculating Deflection Angle
Zonghai Li
In this paper, we introduce a method for calculating the deflection angle in the weak-field approximation, applicable to both null and timelike rays. By combining the trajectory eq…

Generating New Spacetimes through Zermelo Navigation
Zonghai Li, Junji Jia
Zermelo navigation is not only a fundamental tool in Finsler geometry but also a fundamental approach to the geometrization of dynamics in physics. In this paper, we consider the Z…
