Quantum aspects of black hole entropyPARTHASARATHI MAJUMDAR The Institute of Mathematical Sciences, CIT Campus, Chennai 600 113, India Email: partha@imsc.ernet.in Abstract. This survey intends to cover recent approaches to black hole entropy which attempt to go beyond the standard semiclassical perspective. Quantum corrections to the semiclassical Bekenstein--Hawking area law for black hole entropy, obtained within the quantum geometry framework, are treated in some detail. Their ramification for the holographic entropy bound for bounded stationary spacetimes is discussed. Four dimensional supersymmetric extremal black holes in string-based N = 2 supergravity are also discussed, albeit more briefly. Keywords: Bekenstein--Hawking area law; Chern--Simons theory; conformal blocks. Pacs No. 04.70Dy |
