Amnon Neeman, Andrew Ranicki, Aidan Schofield
Every finitely presented algebra S is shown to be Morita equivalent to the universal localization σ^{-1}R of a finite dimensional algebra R. The construction provides many examples…

Semi-invariants of quivers for arbitrary dimension vectors
Aidan Schofield, Michel Van den Bergh
The representations of dimension vector of the quiver Q can be parametrised by a vector space on which an algebraic group $\Gl(α)$ acts so that the set of orbits is bi…
