Hawking radiation and Page curve of regular black holes

Abstract We discuss the information paradox and its implications for regular black holes. Our primary focus is on Page curve using the island treatment and analyzing relevant parameters like Page time and scrambling time. Calculations without considering the island show that the entanglement entropy increases linearly and continues to infinity. When we consider the generalized entropy, we find that the island extends just beyond the horizon, leading to a constant entanglement entropy. Specifically, we find that in the early stages, the island never forms, regardless of the charge and mass configuration of the black hole.
