On Hochschild invariants of Landau–Ginzburg orbifolds
On Hochschild invariants of Landau–Ginzburg orbifolds
We develop an approach to calculating the cup and cap products on Hochschild cohomology and homology of curved algebras associated with polynomials and their finite abelian symmetry groups. For polynomials with isolated critical points, the approach yields a complete description of the products. We also reformulate the result for the …
