Rigidity of Ext and Tor via flat-cotorsion theory
Lars Winther Christensen, Luigi Ferraro, Peder Thompson
Let p be a prime ideal in a commutative noetherian ring R and denote by k(p) the residue field of the local ring R_p. We prove that if an R-module M satisfies Ext_R^n(k(p),M) = 0 f…
The homotopy Lie algebra of a Tor-independent tensor product
Luigi Ferraro, Mohsen Gheibi, David A. Jorgensen +2
In this article we investigate a pair of surjective local ring maps and their relation to the canonical projection , where …
The Taylor resolution over a skew polynomial ring
Luigi Ferraro, Desiree Martin, W. Frank Moore
Let be a field and let be a monomial ideal in the polynomial ring . In her thesis, Taylor introduced a complex which provides a finite free res…
The Eliahou-Kervaire resolution over a skew polynomial ring
Luigi Ferraro, Alexis Hardesty
In a 1987 paper, Eliahou and Kervaire constructed a minimal resolution of a class of monomial ideals in a polynomial ring, called stable ideals. As a consequence of their construct…
Support varieties over skew complete intersections via derived braided Hochschild cohomology
Luigi Ferraro, W. Frank Moore, Josh Pollitz
In this article we study a theory of support varieties over a skew complete intersection , i.e. a skew polynomial ring modulo an ideal generated by a sequence of regular normal…
