Calabi-Yau Frobenius algebras
Ching-Hwa Eu, Travis Schedler
We define Calabi-Yau and periodic Frobenius algebras over arbitrary base commutative rings. We define a Hochschild analogue of Tate cohomology, and show that the "stable Hochschild…

Koszulity and the Hilbert series of preprojective algebras
Pavel Etingof, Ching-Hwa Eu
The goal of this paper is to prove that if Q is a connected non-Dynkin quiver then the preprojective algebra of Q over any field k is Koszul, and has Hilbert series 1/(1-Ct+t^2), w…
