On low degree regular sequences in group cohomology
Mikael Johansson
We investigate small -groups with cohomology rings of depth higher than predicted by Duflot's theorem. In these groups, a sampling would suggest several naive conjectures about…

Computation of Poincare-Betti series for monomial rings
Mikael Johansson
The multigraded Poincare-Betti series P_R^k(x_1,...,x_n; t) of a monomial ring k[x_1,...,x_n]/<M> on a finite number of monomial generators has the form (1+tx_1)(1+tx_2)...(1+tx_n)…
