Abstract

In this paper, we calculate the topological free energy for a number of Yang-Mills-Chern-Simons-matter theories at large and fixed Chern-Simons levels. The topological free energy is defined as the logarithm of the partition function of the theory on with a topological A-twist along and can be reduced to a matrix integral by exploiting the localization technique. The theories of our interest are dual to a variety of Calabi-Yau four-fold singularities, including a product of two asymptotically locally Euclidean singularities and the cone over various well-known homogeneous Sasaki-Einstein seven-manifolds, , , and . We check that the large topological free energy can be matched for theories which are related by dualities, including mirror symmetry and duality.
