We construct several pairwise-incomparable bounds on the projective dimensions of edge ideals. Our bounds use combinatorial properties of the associated graphs; in particular we draw heavily from theâ€¦ (More)

Let R be a hypersurface in an equicharacteristic or unramified regular local ring. For a pair of modules (M, N) over R we study applications of rigidity of TorR(M, N), based on ideas by Huneke,â€¦ (More)

Let R be a local complete intersection and M, N are R-modules such that l(Tor i (M, N)) < âˆž for i â‰« 0. Imitating an approach by Avramov and Buchweitz, we investigate the asymptotic behavior of l(Torâ€¦ (More)

We study obstructions to existence of non-commutative crepant resolutions, in the sense of Van den Bergh, over local complete intersections.

Let R be a Cohen-Macaulay ring and M a maximal CohenMacaulay R-module. Inspired by recent striking work by Iyama, BurbanIyama-Keller-Reiten and Van den Bergh we study the question of when theâ€¦ (More)

We study two properties of modules over an equicharacteristic or unramified local hypersurface R: decency and rigidity. We show that the vanishing of Hochsterâ€™s function Î¸(M, N), known to implyâ€¦ (More)

It is well-known that for a big class of local rings of positive characteristic, including complete intersection rings, the Frobenius endomorphism can be used as a test for finite projectiveâ€¦ (More)

In this paper we give new upper bounds on the regularity of edge ideals whose resolutions are k-steps linear; surprisingly, the bounds are logarithmic in the number of variables. We also give variousâ€¦ (More)

We have identified the origin of the bias instability of the laser gyroscope, which included the ring heliumneon laser with mechanical dither. The data observed consist of the gyro counts of verticalâ€¦ (More)

Let T be a Noetherian ring and f a nonzerodivisor on T . We study concrete necessary and sufficient conditions for a module over R = T/(f) to be weakly liftable to T , in the sense of Auslander,â€¦ (More)
