Entropy ofN=2black holes and theirMbrane description

Abstract
In this paper we discuss the Mbrane description for an N=2 black hole. This solution is a result of the compactification of M5brane configurations over a Calabi-Yau threefold with arbitrary intersection numbers CABC. In analogy with the Dbrane description where one counts open string states we count here open M2branes which end on the M5brane.
