Study evaluates topological contributions in massive SQCD on compact 4-manifolds.
problem Analyzing topological path integrals for massive SQCD with up to 3 massive hypermultiplets.
method Decouples hypermultiplets, evaluates massless limit, and merges singularities at Argyres-Douglas points. Uses mass expansions for and .
result Physical partition functions match mathematical results on Segre numbers of instanton moduli spaces.
