Compatibility conjecture for quantization and reduction via adapted formality
Compatibility conjecture for quantization and reduction via adapted formality
Let be a Poisson manifold with a Lie algebra -action, let be an equivariant momentum map, and let denote the reduced space. Let be a -adapted morphism, and let be the -quasi-isomorphism obtained by the stated zig-zag, with both morphisms constructed using the same Drinfel'd associator. The associated twisted curved morphism is
The reduction maps and fit into a diagram with whose curved -morphism square commutes up to homotopy.
