The Fsignature and strong Fregularity
(200211)We show that the Fsignature of a local ring of characteristic p, defined by Huneke and Leuschke, is positive if and only if the ring is strongly Fregular. 
The structure of Fpure rings
(200310)For a reduced Ffinite ring R of characteristic p >0 and q=p^e one can write R^{1/q} = R^{a_q} \oplus M_q, where M_q has no free direct summands over R. We investigate the structure of Ffinite, Fpure rings R by studying ... 
When does the Fsignature exist?
(200502)We show that the Fsignature of an Ffinite local ring R of characteristic p > 0 exists when R is either the localization of an Ngraded ring at its irrelevant ideal or QGorenstein on its punctured spectrum. This extends ...
