NT=4 equivariant extension of the 3D topological model of Blau and Thompson

Abstract

The Blau–Thompson N T =2, D=3 non-equivariant topological model, obtained through the so-called ‘novel’ twist of N=4, D=3 super-Yang–Mills theory, is extended to a N T =4, D=3 topological theory. The latter, formally, may be regarded as a topological non-trivial deformation of the N T =2, D=4 Yamron–Vafa–Witten theory after dimensional reduction to D=3. For completeness also the dimensional reduction of the half-twisted N T =2, D=4 Yamron model is explicitly constructed.
