Representation Type of EI-Categories
Karsten Dietrich
EI-categories are a simultaneous generalisation of finite groups and finite quivers without oriented cycles. It is therefore a natural question to ask for a characterisation of fin…

The finitistic dimension of algebras with a directed stratification]
Karsten Dietrich
We introduce the notion of a directed stratification for a finite-dimensional algebra. For algebras that admit such a stratification we characterise the projective resolutions of f…

An upper bound for the finitistic dimension of an EI category algebra
Karsten Dietrich
EI categories can be thought of as amalgams of finite posets and finite groups and therefore the associated algebras are built up from incidence algebras and group algebras of fini…
