Abstract
Let be a finite-dimensional (Artinian) Gorenstein algebra, and let denote the connected component of the identity in the automorphism group of . We introduce a new subclass of Gorenstein algebras and prove that for any algebra in this subclass, the group is solvable. This result is closely related to the Christophersen problem in the theory of local algebras.
