چکیده
Definition 1.1 [5] Fix a degree n line bundle ~ on E. Set V = H ~ (E, ~ ) . Identify V| with H~174 Define the shifted diagonal A~:={(x,x+ (n-2)r) lx~E}. Denote by M the set of fixed points for the involution (x, y) ~ (y + 2r, x 2r) on E • E. We say that a divisor D on E • E is allowable if D is stable under this involution, and M occurs in D with even multiplicity. The n-dimensional Sklyanin algebra associated to (E, r) is defined to be the quotient of the tensor algebra,

This paper studies point modules and line modules over the algebra deened by E.K. Sklyanin in 17]. It was proved in 21] that the point modules are in bijection with the points of an elliptic curve E in P 3 together with 4 other points. Here it is p...
متن کاملSome Finite Dimensional Algebras Related to Elliptic Curves
The Koszul dual of a Sklyanin algebra A is a nite dimensional graded algebra depending on an elliptic curve, a translation automorphism, and an integer n 3; it may be deened as Ext A (k;k). The representation theory and structure of these algebras is studied by using the functor Ext A (?; k) to transfer results from the Sklyanin algebras to the nite dimensional algebras. We show that their repr...
متن کاملSome Properties of $ ast $-frames in Hilbert Modules Over Pro-C*-algebras
In this paper, by using the sequence of adjointable operators from pro-C*-algebra $ mathcal{A} $ into a Hilbert $ mathcal{A} $-module $ E $. We introduce frames with bounds in pro-C*-algebra $ mathcal{A} $. New frames in Hilbert modules over pro-C*-algebras are called standard $ ast $-frames of multipliers. Meanwhile, we study several useful properties of standard $ ast $-frames in Hilbert modu...
متن کاملDegenerate Sklyanin Algebras and Generalized Twisted Homogeneous Coordinate Rings
In this work, we introduce the point parameter ring B, a generalized twisted homogeneous coordinate ring associated to a degenerate version of the three-dimensional Sklyanin algebra. The surprising geometry of these algebras yields an analogue to a result of Artin-Tatevan den Bergh, namely that B is generated in degree one and thus is a factor of the corresponding degenerate Sklyanin algebra.
متن کاملRepresentation Theory of Three-dimensional Sklyanin Algebras
Abstract. We determine the dimensions of the irreducible representations of the Sklyanin algebras with global dimension 3. This contributes to the study of marginal deformations of the N=4 super Yang-Mills theory in four dimensions in supersymmetric string theory. Namely, the classification of such representations is equivalent to determining the vacua of the aforementioned deformed theories. W...
