Külshammer ideals of graded categories and Hochschild cohomology
Volkov, Yury · Zvonareva, Alexandra
Original · EN
We generalize the notion of Külshammer ideals to the setting of a graded category. This allows us to define and study some properties of Külshammer type ideals in the graded center of a triangulated category and in the Hochschild cohomology of an algebra, providing new derived invariants. Further properties of Külshammer ideals are studied in the case where the category is d-Calabi-Yau.
