Homogeneity of cohomology classes associated with Koszul matrix factorizations
Homogeneity of cohomology classes associated with Koszul matrix factorizations
In this work we prove the so-called dimension property for the cohomological field theory associated with a homogeneous polynomial $W$ with an isolated singularity, in the algebraic framework of [A. Polishchuk and A. Vaintrob, Matrix factorizations and cohomological field theories , J. Reine Angew. Math. 714 (2016), 1–122]. This amounts …
