Abstract
In a recent work with Pedro Macias Marques and Jerzy Weyman we prove that Artinian Gorenstein algebras of codepth four and socle degree three are obtained by a doubling construction from generically Gorenstein rings of codepth three. In this talk, based on a joint work with Jai Laxmi, I will discuss how the Tor Algebra structure transfers from one ring to another through this construction.
