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

The Blau–Thompson NT=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 NT=4, D=3 topological theory. The latter, formally, may be regarded as a topological non-trivial deformation of the NT=2, D=4 Yamron–Vafa–Witten theory after dimensional reduction to D=3. For completeness also the dimensional reduction of the half-twisted NT=2, D=4 Yamron model is explicitly constructed.
