Entropy of N=2 black holes and their M-brane description
Klaus Behrndt, Thomas Mohaupt
TL;DR
This paper explores the M-brane description of an N=2 black hole, focusing on counting open 2-branes ending on M-5-branes resulting from compactification over Calabi-Yau threefolds.
Contribution
It introduces a novel M-brane framework for N=2 black holes, extending the analogy of D-brane open string counting to open 2-branes on M-5-branes.
Findings
Provides a method to count open 2-branes in M-theory
Connects black hole entropy to M-brane configurations
Generalizes D-brane open string counting to M-branes
Abstract
In this paper we discuss the M-brane description for a N=2 black hole. This solution is a result of the compactification of M-5-brane configurations over a Calabi-Yau threefold with arbitrary intersection numbers . In analogy to the D-brane description where one counts open string states we count here open 2-branes which end on the M-5-brane.
