In [K. R. Fuller, on indecomposable injectives over artinian rings, Pacific J. Math. 29 (1969), 115-135, Theorem 3.1] K. R.

Quadratic Geometries, Projective Modules
✍ R. Gow; W. Willems πŸ“‚ Article πŸ“… 1993 πŸ› Elsevier Science 🌐 English βš– 463 KB

Let \(G\) be a finite group and let \(k\) be a field. We say that a \(k G\)-module \(V\) has a quadratic geometry or is of quadratic type if there exists a non-degenerate (equivalently non-singular) \(G\)-invariant quadratic form on \(V\). If \(V\) is irreducible or projective indecomposable and \(k

We show that if \(\phi\) is a Drinfeld \(A\)-module over a field \(L\), then any polynomial \(g(x) \in L[x]\) which maps the a-torsion into itself for all \(a \in A\) must be an endomorphism of \(\phi\). In generic characteristic, we prove a stronger result: if there is an infinite \(A\)-submodule \

Relative singularity categories and Gore

## Abstract We introduce the notion of relative singularity category with respect to a self‐orthogonal subcategory Ο‰ of an abelian category. We introduce the Frobenius category of ω‐Cohen‐Macaulay objects, and under certain conditions, we show that the stable category of ω‐Cohen‐Macaulay objects is
