On Gerko's Strongly Tor-independent Modules

Hannah Altmann, Sean K. Sather-Wagstaff

Gerko proves that if an artinian local ring possesses a sequence of strongly Tor-independent modules of length , then . This general…

Applications of Differential Graded Algebra Techniques in Commutative Algebra

Saeed Nasseh, Sean K. Sather-Wagstaff

Differential graded (DG) algebras are powerful tools from rational homotopy theory. We survey some recent applications of these in the realm of homological commutative algebra.

Ladder determinantal rings over normal domains

Sean K. Sather-Wagstaff, Tony Se, Sandra Spiroff

We explicitly describe the divisor class groups and semidualizing modules for ladder determinantal rings with coefficients in an arbitrary normal domain for arbitrary ladders, not…

Generic Constructions and Semidualizing Modules

Sean K. Sather-Wagstaff, Tony Se, Sandra Spiroff

We investigate some general machinery for describing semidualizing modules over generic constructions like ladder determinantal rings with coefficients in a normal domain. We also…

Ascent Properties for Test Modules

Sean K. Sather-Wagstaff

We investigate modules for which vanishing of Tor-modules implies finiteness of homological dimensions (e.g., projective dimension and G-dimension). In particular, we answer a ques…

Irreducible divisor pair domains

Sean K. Sather-Wagstaff

We introduce and study a new class of integral domains which we call irreducible divisor pair domains (IDPDs). In particular, we show how IDPDs fit in with other classes of integra…
