Corrections to Macroscopic Supersymmetric BlackHole Entropy
, 1998
"... We determine the corrections to the entropy of extremal black holes arising from terms quadratic in the Riemann tensor in N = 2; D = 4 supergravity theories. We follow Wald's proposal to modify the BekensteinHawking area law. The new entropy formula, whose value only depends on the electric/ma ..."

Deviations from the Area Law for Supersymmetric Black Holes
, 1999
"... We review modifications of the BekensteinHawking area law for black hole entropy in the presence of higherderivative interactions. In fourdimensional N = 2 compactifications of string theory or Mtheory these modifications are crucial for finding agreement between the macroscopic entropy obtained ..."

to incorporate nonholomorphic corrections. March 1999 a cardoso@phys.uu.nl b bdewit@phys.uu.nl c mohaupt@hera1.physik.unihalle.de 1 Introduction It is one of the most intriguing properties of black holes in general relativity that one can derive a set of laws, called the laws of black hole mechanics
Dual Heterotic BlackHoles in Four and Two Dimensions
, 1998
"... We consider a class of extremal and nonextremal fourdimensional blackhole solutions occuring in toroidally compactified heterotic string theory, whose tendimensional interpretation involves a KaluzaKlein monopole and a fivebrane. We show that these fourdimensional solutions can be connected to ..."

transformations in four dimensions. These transformations are implemented by performing a reduction on a twotorus with Lorentzian signature. We argue that the same mechanism can be applied to extremal and nonextremal blackhole solutions in the FHSV model. June 1998 a cardoso@phys.uu.nl b mohaupt@hera1
Recurrence relations for radial wave functions for the Nth dimensional oscillators and hydrogenlike atoms
 J. Phys. A: Math. Gen
"... Abstract. Using a general procedure for nding recurrence relations for hypergeometric functions and polynomials introduced by Cardoso et al. [J. Phys. A 36 (2003), 20552068] we obtain some new recurrence relations for the radial wave functions of the Nth dimensional isotropic harmonic oscillators ..."
