Abstract

We consider a cobordism category whose morphisms are punctured connect sums of S1×S2S^1 \times S^2's (wormhole spaces) with embedded admissibly colored banded trivalent graphs. We define a TQFT on this cobordism category over the field of rational functions in an indeterminant A.A. For rr large, we recover, by specializing AA to a primitive 4rth root of unity, the Witten-Reshetikhin-Turaev TQFT restricted to links in wormhole spaces. Thus, for rr large, the rrth Witten-Reshetikhin-Turaev invariant of a link in some wormhole space, properly normalized, is the value of a certain rational function at eπi2r.e^{\frac{\pi i}{2r}}. We relate our work to Hoste and Przytycki's calculation of the Kauffman bracket skein module of S1×S2.S^1 \times S^2.
