The formal-dissection realization conjecture for derived-equivalent gentle and skew-gentle algebras
Let be a graded gentle or skew-gentle algebra, and let be the graded surface associated to . For a formal dissection of , let be its associated formal differential graded algebra. Formal-dissection realization conjecture. For any graded associative algebra which is (perfect) derived equivalent to , there exists a formal dissection of such that
as graded associative algebras. This conjecture is presented as a converse to the theorem that formal dissections yield graded skew-gentle algebras and that formal-generator endomorphism algebras are derived equivalent to graded skew-gentle algebras. Its general status is not specified in the supplied text.
