Non-exact wrapped Fukaya category and deformed multiplicative preprojective algebra
Non-exact wrapped Fukaya category and deformed multiplicative preprojective algebra
Let be the resolution of the surface singularity, let be the indicated divisor, and let be a formal parameter with coefficient field . Set . Non-exact wrapped Fukaya equivalence conjecture. The perfect derived non-exact wrapped Fukaya category satisfies
with . This would provide the missing categorical computation in the non-exact setting and extend the exact-case identification to deformed multiplicative preprojective algebras; the paper notes that foundational ingredients for the non-exact category remain unavailable.
