| Abstract: | The aim of this article is to study the homological properties of deficiently extremal Gorenstein algebras. We prove that
if R/I is an odd deficiently extremal Gorenstein algebra with pure minimal free resolution, then the codimension of R/I must be odd. As an application, the structure of pure minimal free resolution of a nearly extremal Gorenstein algebra is
obtained. |
