Bethe/Gauge correspondence on curved spaces

Understand

Bethe/gauge correspondence identifies supersymmetric vacua of massive gauge theories invariant under the two dimensional N=2 Poincare supersymmetry with the stationary states of some quantum integrable system.

• The supersymmetric theory can be twisted in a number of ways, producing a topological field theory.
• For these theories we compute the handle gluing operator H.
• We also discuss the Gaudin conjecture on the norm of Bethe states and its connection to H.
