Distinct topological functionals from inequivalent enriched TQFTs

About 3 years old · traced to

Let YY be an nn-finite space, meaning that π0Y\pi_0Y and all homotopy groups πq(Y,y)\pi_q(Y,y) for 0≤q≤n0\leq q\leq n and y∈Yy\in Y are finite. An nn-dimensional bosonic or fermionic YY-enriched fully extended TQFT is a theory whose partition function defines the corresponding topological functional to YY. Distinct-functional conjecture. Inequivalent nn-dimensional bosonic, respectively fermionic, YY-enriched fully extended TQFTs produce different nn-dimensional bosonic, respectively fermionic, topological functionals to YY. This asserts completeness of partition functions as invariants of these theories, but the source gives no resolution of the conjecture.
