G-crossed tensor-category conjecture for twisted modules
G-crossed tensor-category conjecture for twisted modules
Let be a vertex operator algebra satisfying the first two conditions of the twisted intertwining-operator conjecture: is simple with , for , contragredient , and is -cofinite. Let be a finite group of automorphisms of . Consider the category whose objects are grading-restricted generalized -twisted -modules for all .
G-crossed tensor-category conjecture. This category has a natural structure of a -crossed tensor category satisfying additional properties.
The conjecture extends the expected orbifold tensor-category structure beyond the completely reducible setting. The supplied text gives no resolution evidence.
