Title: Part I: Black Hole Entropy

Abstract: What can it mean to attribute a physical entropy to a vacuum region of spacetime—such as a black hole—in the semi-classical regime, where the spacetime geometry is treated classically?  In this talk, I give an exposition and analysis of a number of conceptual and foundational problems attending such attributions.  I address, inter alia, questions about: how one might try to justify such attributions; the type of entropy at issue (thermodynamical, Gibbsian, Boltzmannian, entanglement, holographic,…); and what the physical significance of such attributions may be.  I conclude with speculative remarks on a few larger philosophical issues about the nature of entropy and of spacetime that the attribution raises.”
