  • Alim, Murad; Cecotti, Sergio; Cordova, Clay; Espahbodi, Sam; Rastogi, Ashwin; Vafa, Cumrun (Springer, 2012-09-11)
    We study the BPS spectra of N=2 complete quantum field theories in four dimensions. For examples that can be described by a pair of M5 branes on a punctured Riemann surface we explain how triangulations of the surface ...
  • Cecotti, Sergio; Vafa, Cumrun (SISSA, 2011-03-30)
    We define the notion of a complete N=2 supersymmetric theory in 4 dimensions as a UV complete theory for which all the BPS central charges can be arbitrarily varied as we vary its Coulomb branch parameters, masses, ...
  • Bershadsky, M.; Cecotti, Sergio; Ooguri, H.; Vafa, Cumrun (Springer, 1994-10)
    We develop techniques to compute higher loop string amplitudes for twisted $N=2$ theories with $\hat c=3$ (i.e. the critical case). An important ingredient is the discovery of an anomaly at every genus in decoupling of ...
  • Cecotti, Sergio; Cordova, Clay; Heckman, Johnatan J.; Vafa, Cumrun (Springer, 2011-07)
    We introduce T-branes, or "triangular branes," which are novel non-abelian bound states of branes characterized by the condition that on some loci, their matrix of normal deformations, or Higgs field, is upper triangular. ...
