On Gerko's Strongly Tor-independent Modules

Hannah Altmann, Sean K. Sather-Wagstaff

Gerko proves that if an artinian local ring $(R, m_{R})$ possesses a sequence of strongly Tor-independent modules of length $n$ , then $m_{R}^{n} \neq = 0$ . This general…

Lower bounds on projective levels of complexes

Hannah Altmann, Eloísa Grifo, Jonathan Montaño +2

For an associative ring $R$ , the projective level of a complex $F$ is the smallest number of mapping cones needed to build $F$ from projective $R$ -modules. We establish lower bound…

Semidualizing DG Modules over Tensor Products

Hannah Altmann

We study the existence of nontrivial semidualizing DG modules over tensor products of DG algebras over a field. In particular, this gives a lower bound on the number of semidualizi…
