Some non-principal rigid ideals in Gorenstein domains of dimension one

Lars Winther Christensen, Alex Gerko, Srikanth B. Iyengar

We discuss an example of a rigid non-principal ideal in a one dimensional (commutative) Gorenstein domain, which contradicts a conjecture of C. Huneke and R. Wiegand. The construct…

The spectrum of local dualisable modular representations

Dave Benson, Srikanth B. Iyengar, Henning Krause +1

For a point in the spectrum of the cohomology ring of a finite group over a field , we calculate the spectrum for the subcategory of dualisable objects inside…

A freeness criterion for complexes with derived actions

Sylvain Brochard, Srikanth B. Iyengar, Chandrashekhar B. Khare

Inspired by the patching method of Calegari and Geraghty, and a conjecture of de Smit that has been proved by the first author, we present a conjectural freeness criterion without…

Locally dualisable modular representations and local regularity

Dave Benson, Srikanth B. Iyengar, Henning Krause +1

This work concerns the stable module category of a finite group over a field of characteristic dividing the group order. The minimal localising tensor ideals correspond to the non-…

Non-existence of Ulrich modules over Cohen-Macaulay local rings

Srikanth B. Iyengar, Linquan Ma, Mark E. Walker +1

Over a Cohen-Macaulay local ring, the minimal number of generators of a maximal Cohen-Macaulay module is bounded above by its multiplicity. In 1984 Ulrich asked whether there alway…

Locally dualizable modules abound

Jon F. Carlson, Srikanth B. Iyengar

It is proved that given any prime ideal of height at least 2 in a countable commutative noetherian ring , there are uncountably many more dualizable objects in th…
