Rigidity dimension - a homological dimension measuring resolutions of algebras by algebras of finite global dimension Open
A new homological dimension is introduced to measure the quality of resolutions of `singular' finite dimensional algebras (of infinite global dimension) by `regular' ones (of finite global dimension). Upper bounds are established in terms …

Thick Subcategories of the stable category of modules over the exterior algebra Open
We study thick subcategories defined by modules of complexity one in $\underline{\md}R$, where $R$ is the exterior algebra in $n+1$ indeterminates.

Canonical bimodules and dominant dimension Open
For a finite dimensional algebra $A$ over a field $k$, the inherent $A$-bimodules which include $A$ and its $k$-dual $\mathrm {D}(A)$, as well as those derived from them by iteratively taking their left or right $A$-duals or higher extensi…
