Maps from Feigin and Odesskii's elliptic algebras to twisted homogeneous coordinate rings

Alex Chirvasitu, Ryo Kanda, S. Paul Smith

The elliptic algebras in the title are connected graded $C$ -algebras, denoted $Q_{n, k} (E, τ)$ , depending on a pair of relatively prime integers $n > k \geq 1$ , an elliptic curv…

Projective discrete modules over profinite groups

Alexandru Chirvasitu, Ryo Kanda

We show that the category of discrete modules over an infinite profinite group has no non-zero projective objects and does not satisfy Ab4*. We also prove the same types of results…

Finite quotients of powers of an elliptic curve

Alex Chirvasitu, Ryo Kanda, S. Paul Smith

Let $E$ be an elliptic curve. When the symmetric group $Σ_{g + 1}$ of order $(g + 1)!$ acts on $E^{g + 1}$ in the natural way, the subgroup $E_{0}^{g + 1}$ , consisting of those $(g + 1)$ -tuple…

The characteristic variety for Feigin and Odesskii's elliptic algebras

Alex Chirvasitu, Ryo Kanda, S. Paul Smith

This paper examines an algebraic variety that controls an important part of the structure and representation theory of the algebra $Q_{n, k} (E, τ)$ introduced by Feigin and Odesskii.…
