Witt invariants from q-series $\hat{Z}$ (2204.02794v2)
Published 4 Apr 2022 in math.GT, hep-th, math-ph, math.MP, and math.QA
Abstract: We present a relation between the Witt invariants of 3-manifolds and the $\hat{Z}$-invariants. It provides an alternative approach to compute the Witt invariants of 3-manifolds, which were originally defined geometrically in four dimensions. We analyze various homology spheres including a hyperbolic manifold using this method.
