Adjoint Vector Fields and Differential Operators on Representation Spaces
Let G be a semisimple algebraic group with Lie algebra g. In 1979, J. Dixmier proved that any vector field annihilating all G-invariant polynomials on g lies in the k[g]module generated by the ”adjoint vector fields”, i.e., vector fields ς of the form ς(y)(x) = [x, y], x, y ∈ g. A substantial generalisation of Dixmier’s theorem was found by Levasseur and Stafford. They explicitly described the ...
متن کاملSpectral Operators in a Direct Sum of Hilbert Spaces.
Let E C X be the finite-dimensional subspace spanned by xi, ..., xm. Now, for y E Y and variable x e E, y(x) is a continuous linear functional on E which we denote by y'. Thus, there is defined in a natural way a function f'(x) with domain (E n B) and range in E*, the conjugate space of E. The domain contains and surrounds densely every point of E n K(D), hence every point of K(E n D). It is ea...
متن کاملNon-self-adjoint Differential Operators
We describe methods which have been used to analyze the spectrum of non-self-adjoint differential operators, emphasizing the differences from the self-adjoint theory. We find that even in cases in which the eigenfunctions can be determined explicitly, they often do not form a basis; this is closely related to a high degree of instability of the eigenvalues under small perturbations of the opera...
متن کاملAdjoint for Operators in Banach Spaces
In this paper we show that a result of Gross and Kuelbs, used to study Gaussian measures on Banach spaces, makes it possible to construct an adjoint for operators on separable Banach spaces. This result is used to extend well known theorems of von Neumann and Lax. We also partially solve an open problem on the existence of a Markushevich basis with unit norm and prove that all closed densely de...
متن کاملAdjoint and self - adjoint differential operators on graphs ∗
A differential operator on a directed graph with weighted edges is characterized as a system of ordinary differential operators. A class of local operators is introduced to clarify which operators should be considered as defined on the graph. When the edge lengths have a positive lower bound, all local self-adjoint extensions of the minimal symmetric operator may be classified by boundary condi...
