Strong formality conjecture for the half-quantum flag variety
Strong formality conjecture for the half-quantum flag variety
Let be an almost-simple algebraic group with dual group , let be a chosen complex root of unity, let be the half-quantum flag variety, let be the Springer resolution, and let be the nilpotent cone. Write for the derived infinity-category of quasi-coherent sheaves on , for the formal cocompletion of coherent dg sheaves, and for the formal cocompletion of finite-dimensional dg representations of the small quantum group. Strong formality conjecture. There is a -linear, fully faithful, central tensor functor
and a corresponding fully faithful tensor functor
The conjecture is motivated by the enhanced derived category of , the computation relating its derived endomorphisms to the Springer resolution, and known formality results.
