Little Strings, Quasi-topological Sigma Model on Loop Group, and Toroidal Lie Algebras

Meer Ashwinkumar, Jingnan Cao, Yuan Luo +2

We study the ground states and left-excited states of the A_{k-1} N=(2,0) little string theory. Via a theorem by Atiyah [1], these sectors can be captured by a supersymmetric nonli…
