The Algebra & Number Theory Seminar meets Mondays at 3:00 pm during the semester. Talks will be given online via Zoom or in person; please check the specific week's talk. If you would like to give a talk in the seminar please contact Lars Winther Christensen at lars.w.christensen@ttu.edu
Levels are a numerical invariant of complexes that are defined by
using the triangulated structure of the derived category. Levels with
respect to a ring have been studied extensively, and have been used to
show that a commutative noetherian ring R is regular if and only if
there is an upper bound on the R-level of perfect R-complexes. In this
talk we discuss a Gorenstein version of this fact. This is joint work
with Lars Winther Christensen, Antonia Kekkou, and Justin Lyle.
