Homology multipliers and the relation type of parameter ideals
(200501)We study the relation type question, raised by C. Huneke, which asks whether for a complete equidimensional local ring R there exists a uniform bound for the relation type of parameter ideals. Wang gave a positive answer ... 
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 ...
