Partition functions of reduced matrix models with classical gauge groups Original Research Article

We evaluate partition functions of matrix models which are given by topologically twisted and dimensionally reduced actions of image image super-Yang–Mills theories with classical (semi-)simple gauge groups, image, image and image. The integrals reduce to those over the maximal tori by semi-classical approximation which is exact in reduced models. We carry out residue calculus by developing a diagrammatic method, in which the action of the Weyl groups and therefore counting of multiplicities are explained obviously.
