报告摘要: 

Finsler geometry is a natural generalization of Riemannian geometry with the latter as a special case. Trajectories of Spacetime play an important role in studying the gravitational waves and black hole shadows. In this talk, I will discuss our recent works on studying the orbits of Finslerian Schwarzschild black holes. First, I will introduce basic concepts of Finsler geometry and the derived Finslerian Schwarzschild black hole solution. Second, I will discuss the constraint on Finslerian Schwarzschild black hole by the observation of orbital precession of the star S2 of Sgr A*. Third, I will give necessary condition for the orbits of a Finslerian Schwarzschild black hole to be closed. At last, Shadows of Finslerian Schwarzschild black hole will be discussed.
