Power series rings and projectivity

R. -O. Buchweitz, H. Flenner

We show that a formal power series ring over a noetherian ring is not a projective module unless is artinian. However, if is local, then $A[[X]…

Linear free divisors and quiver representations

Ragnar-Olaf Buchweitz, David Mond

Linear free divisors are free divisors, in the sense of K.Saito, with linear presentation matrix (example: normal crossing divisors). Using techniques of deformation theory on repr…

Factoring the Adjoint and Maximal Cohen--Macaulay Modules over the Generic Determinant

Ragnar-Olaf Buchweitz, Graham J. Leuschke

A question of Bergman asks whether the adjoint of the generic square matrix over a field can be factored nontrivially as a product of square matrices. We show that such factorizati…
