Page curve and island in EGB gravity

In this paper, the information paradox on lower-dimensional Gauss–Bonnet gravity, known as a three-dimensional EGB black hole, is studied using quantum extremal island approach. For that, we connect an auxiliary flat bath system to timelike singularity spacetime and estimate entropy of hawking radiation in its asymptotic regions when gravity weak. The addition areas entanglement wedge causes obey Page curve, shown. surface, or boundary, outside horizon. This yields time-independent equation for Hawking fine-grained compatible with appropriate curve. We also discover modifications time.
