The existence and distribution of photon spheres near spherically symmetric black holes: a geometric analysis
Abstract Photon sphere has attracted significant attention since the capture of black hole shadow images by Event Horizon Telescope. Recently, a number of studies have highlighted that the number of photon spheres and their distributions near black holes are strongly constrained by black hole proper...
