Equivalence of the semisimplification with the Verlinde quotient

About 8 years old · traced to

Let HVH_V be the reductive algebraic group and let C‾Vψ‾\overline{\mathcal{C}}_{\overline{V_\psi}} be the semisimplification of the tensor category generated by the corresponding object Vψ‾\overline{V_\psi}. For sufficiently large primes pp, there is a surjective tensor functor

F:Verp(HV)→C‾Vψ‾.F:{\rm Ver}_p(H_V)\to \overline{\mathcal{C}}_{\overline{V_\psi}}.

Equivalence conjecture. For sufficiently large pp, the functor FF is an equivalence.

The preceding theorem establishes that the target is a quotient of Verp(HV){\rm Ver}_p(H_V) and, in particular, a fusion category; the conjecture asserts that this quotient has no further nontrivial kernel.
