On the combinatorics of extensions of preinjective Kronecker modules

Abstract We explore the combinatorial properties of a particular type of extension monoid product of preinjective Kronecker modules. The considered extension monoid product plays an important role in



Subrepresentations of Kronecker representations

On preprojective short exact sequences in the Kronecker case

On Degenerations and Extensions of Finite Dimensional Modules

Abstract We derive a cancellation theorem for degenerations of modules that says in particular, that projective or injective common direct summands can always be neglected. Combining the cancellation

Combinatorics of Column Minimal Indices and Matrix Pencil Completion Problems

The possible Kronecker invariants of a matrix pencil with a prescribed sub pencil, when the prescribed subpencil has only column (row) minimal indices as Kr one-size-fits-all indices is described.

The Monoid of Families of Quiver Representations

A monoid structure on families of representations of a quiver is introduced by taking extensions of representations in families, that is, subvarieties of the varieties of representations. The study

Representation Theory of Artin Algebras I

This is the first of a series of papers dealing with the representation theory of artin algebras, where by an artin algebra we mean an artin ring having the property that its center is an artin ring
