Abstract

Extremal black holes in M-theory compactification on are microscopically represented by fivebranes wrapping , where is a Calabi-Yau threefold and is a four-cycle in . Additional spacetime charges arise from momentum around the and expectation values for the self-dual three-form field strength in the fivebrane. The microscopic entropy of the fivebrane as a function of all the charges is determined from a two-dimensional sigma model whose target space includes the fivebrane moduli space. This entropy is compared to the macroscopic formula. Precise agreement is found for both the tree-level and one-loop expressions.
