Noncommutative unfolding of hypersurface singularity

Vladimir Hinich, Dan Lemberg

Research output: Contribution to journalArticlepeer-review


A version of Kontsevich formality theorem is proven for smooth DG algebras. As an application of this, it is proven that any quasiclassical datum of noncommutative unfolding of an isolated surface singularity can be quantized.
