CLASSICAL AND QUANTUM ASPECTS OF 4-DIMENSIONAL BLACK-HOLES

In this talk I address some aspects in the recent developments for N = 2 black holes in 4 dimensions. I restrict myself on axion-free soluti ons that can classically be related to intersections of isotropic D- o r M-branes. After reviewing of some classical properties I include cor rections coming from a general cubic prepotential. Ori the heterotic s ide these are quantum corrections for these black hole solutions. Fina lly, I discuss a microscopic interpretation of the entropy for the ext remal as well as near-extremal black hole.
