Mad Subalgebras of Rings of Differential Operators on Curves

چکیده
We study the maximal abelian ad-nilpotent (mad) subalgebras of the domains D Morita equivalent to the first Weyl algebra. We give a complete description both of the individual mad subalgebras and of the space of all such. A surprising consequence is that this last space is independent of D . Our results generalize some classic theorems of Dixmier about the Weyl algebra.

Weighted Projective Spaces and Minimal Nilpotent Orbits
We investigate (twisted) rings of differential operators on the resolution of singularities of an irreducible component X of Omin ∩ n+ (where Omin is the (Zariski) closure of the minimal nilpotent orbit of sp2n and n+ is the Borel subalgebra of sp2n) using toric geometry, and show that they are homomorphic images of a certain family of associative subalgebras of U(sp2n), which contains the maxi...
متن کاملSymmetry group, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation
In this paper Lie point symmetries, Hamiltonian equations and conservation laws of general three-dimensional anisotropic non-linear sourceless heat transfer equation are investigated. First of all Lie symmetries are obtained by using the general method based on invariance condition of a system of differential equations under a prolonged vector field. Then the structure of symmetry ...
متن کاملLie Subalgebras of Differential Operators on the Super Circle
We classify anti-involutions of Lie superalgebra ŜD preserving the principal gradation, where ŜD is the central extension of the Lie superalgebra of differential operators on the super circle S. We clarify the relations between the corresponding subalgebras fixed by these anti-involutions and subalgebras of ĝl∞|∞ of types OSP and P . We obtain a criterion for an irreducible highest weight modul...
متن کاملInvariant Differential Operators for Non-Compact Lie Groups: Parabolic Subalgebras
In the present paper we start the systematic explicit construction of invariant differential operators by giving explicit description of one of the main ingredients the cuspidal parabolic subalgebras. We explicate also the maximal parabolic subalgebras, since these are also important even when they are not cuspidal. Our approach is easily generalised to the supersymmetric and quantum group sett...
متن کاملThe Spectrum of Difference Operators and Algebraic Curves
led to a theory relating periodic second order (differential and difference) operators to hyperelliptic curves with branch points given by the periodic and antiperiodic spectrum of the original operator. As a result the periodic second order operators with a given spectrum form a torus (except for a lower dimensional submanifold) which is the Jacobi variety of the defining curve. Krichever [15,...
