    • Exact and Asymptotic Degeneracies of Small Black Holes 

      Dabholkar, Atish; Denef, Frederik; Moore, Gregory W.; Pioline, Boris (Institute of Physics, 2005)
      We examine the recently proposed relations between black hole entropy and the topological string in the context of type II/heterotic string dual models. We consider the degeneracies of perturbative heterotic BPS states. ...

    • Precision Counting of Small Black Holes 

      Dabholkar, Atish; Denef, Frederik; Moore, Gregory W.; Pioline, Boris (Institute of Physics, 2005)
      It has recently been proposed that a class of supersymmetric higher-derivative interactions in Script N = 2 supergravity may encapsulate an infinite number of finite size corrections to the microscopic entropy of certain ...

    • Supersymmetric Gauge Theories, Intersecting Branes and Free Fermions 

      Dijkgraaf, Robbert; Hollands, Lotte; Sulkowski, Piotr; Vafa, C. (American Physical Society, 2008)
      We show that various holomorphic quantities in supersymmetric gauge theories can be conveniently computed by configurations of D4-branes and D6-branes. These D-branes intersect along a Riemann surface that is described by ...
