Recent Papers and Preprints
Stable projective homotopy theory of modules, tails, and Koszul duality (with R. Martinez Villa), 29 pp, to appear in Communications in Algebra. (Version 7.11, Sept. 12, 2009)
1Torsion of finite modules over semiperfect rings, Journal of Algebra, 324 (2010), 25952607.
On Auslander  Buchsbaum  type formulas, 8 pp.
Stability and duality (with I. Reiten), (in preparation).
Deformation Theory (table of contents)
(with A.Vlassov), 5 pp. (Book in preparation)
Linear monoidal structures on module categories, (with A. Vlassov), 15
pp. (In progress)
The representation rings of k[X],
(with A. Vlassov) 4 pp. This is our elementary solution to the
ClebschGordan
problem for the monoidal structures on finitedimensional modules over
the polynomials in one letter. It was obtained in the summer of 1997
and is included in our paper on linear monoidal structures mentioned
above. Because we are getting a steady stream of requests for that
proof and because the paper just keeps growing, we decided to extract
the proof from the paper and place it as a preprint. This version has
been slightly edited to make it selfcontained.
Beyond Vogel cohomology, 7 pp. (To be expanded)
Cohomology
of tails and stable cohomology
over Koszul quiver algebras
(with R. Martinez Villa), Fields Institute Communications, 45 (2005),
299306.
Cohomology
of tails, Tate  Vogel
cohomology, and noncommutative Serre duality over Koszul quiver algebras
(with R. Martinez Villa), Journal
of Algebra, 280 (2005), 5883.
Linkage of modules (with J. Strooker), Journal of
Algebra, 271 (2004), no. 2, 587626.
(This version, dated Jan. 3,
2006, incorporates the corrections
contained in Corrections
to Linkage of Modules.)
Absolute, relative, and Tate cohomology of
modules of finite Gorenstein dimension (with L. Avramov),
Proc. London
