Calabi-Yau structures on categories of matrix factorizations

Published 18 Apr 2016 in math.AG | (1604.05365v1)

Abstract: We write out explicit proper Calabi-Yau structures, i. e. non-degenerate cyclic cocycles on the differential graded categories of matrix factorizations of regular functions with isolated critical points. The formulas involve the Kapustin-Li trace and its "higher corrections".
