Null Geodesics and Repulsive Behavior of Gravity in (2+1)-dimensional Massive Gravity

Keisuke Nakashi, Shinpei Kobayashi, Shu Ueda +1

We study the null geodesics in a static circularly symmetric (SCS) black hole spacetime which is a solution in the $(2+1)$-dimensional massive gravity proposed by Bergshoeff, Hohm…
