Abstract
Black hole information paradox is a well known problem and significant progress was made recently. In particular the island formula for the radiation entropy gives Page curve and therefore maintains unitarity. In this talk I will discuss how to derive Page curve from holography. We provide an explicit construction of gravity system attached with bath based on partial reduction. We compute both entanglement entropy and reflected entropy, and find that they precisely agree with island formula.
