An inductive method for separable deformations
Ariel Amsalem, Yuval Ginosar · The Quarterly Journal of Mathematics · 2024
ABSTRACT The Donald–Flanigan conjecture asserts that any group algebra of a finite group has a separable deformation. We apply an inductive method to deform group algebras from deformations of normal subgroup algebras, establishing an infinite family of metacyclic groups which fulfill the conjecture.
