Title: ceff as a new invariant of 3-manifolds
Abstract: This talk reports on a recent progress towards understanding new structures in low-dimensional topology inspired by physics. Namely, we introduce and study numerical quantity ceff for a closed, oriented 3-manifold M. This has a physical interpretation as a rate of growth of supersymmetric states in gauge theory T[M] corresponding to M. We test several conjectures related to T[M] and ceff for a class of integer homology 3-spheres. Based on arXiv:2508.10087.
