Superstrings in Thermal Anti-de Sitter Space
Sujay K. Ashok, Jan Troost
We revisit the calculation of the thermal free energy for string theory in three-dimensional anti-de Sitter spacetime with Neveu-Schwarz-Neveu-Schwarz flux. The path integral calcu…
On BPS Strings in Yang-Mills Theory
Sujay K. Ashok, Varun Gupta, Nemani V. Suryanarayana
We study singular time-dependent -BPS configurations in the abelian sector of supersymmetric Yang-Mills theory that represent BPS string-like defec…
Surface Defects from Fractional Branes -- I
S. K. Ashok, M. Billo, M. Frau +2
We show that the Gukov-Witten monodromy defects of supersymmetric Yang-Mills theory can be realized in perturbative string theory by considering an orbifold background of the Kanno…
Surface Defects from Fractional Branes -- II
S. K. Ashok, M. Billo, M. Frau +2
A generic half-BPS surface defect of supersymmetric U Yang-Mills theory is described by a partition of and a set of continuous p…
Triangle Groups: Automorphic Forms and Nonlinear Differential Equations
Sujay K. Ashok, Dileep P. Jatkar, Madhusudhan Raman
We study the relations governing the ring of quasiautomorphic forms associated to triangle groups with a single cusp, thereby extending our earlier results on Hecke groups. The Eis…
