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…

Gorenstein weak global dimension is symmetric
Lars Winther Christensen, Sergio Estrada, Peder Thompson
We study the Gorenstein weak global dimension of associative rings and its relation to the Gorenstein global dimension. In particular, we prove the conjecture that the Gorenstein w…
