Skowronski–Weyman theorem
Statement
Let Q be a finite connected quiver. The following are equivalent:
- Q is either a Dynkin quiver or a Euclidean quiver.
- For each dimension vector d, the algebra SI(Q,d) is complete intersection.
- For each dimension vector d, the algebra SI(Q,d) is either a polynomial algebra or a hypersurface.
