Perturbation of Differential Operators Admitting a Continuous Linear Right Inverse on Ultradistributions
Let Pm be a homogeneous polynomial of degree m in n ≥ 2 variables for which the associated partial differential operator Pm(D) admits a continuous linear right inverse on C∞(Rn). Examples suggest that then for each polynomial Q of degree less than m there exists a number 0 < β < 1 such that the operator (Pm+Q)(D) admits a continuous linear right inverse on the space of all ωβ-ultradifferentiabl...
متن کاملOn Commuting Differential Operators
The theory of commuting linear differential expressions has received a lot of attention since Lax presented his description of the KdV hierarchy by Lax pairs (P,L). Gesztesy and the present author have established a relationship of this circle of ideas with the property that all solutions of the differential equations Ly = zy, z ∈ C, are meromorphic. In this paper this relationship is explored ...
متن کاملDifferential operators on orbifolds
An algorithm is presented that computes explicit generators for the ring of differential operators on an orbifold, the quotient of a complex vector space by a finite group action. The algorithm also describes the relations among these generators. The algorithm presented in this paper is based on Schwarz’s study of a map carrying invariant operators to operators on the orbifold and on an algorit...
متن کاملInvariant Differential Operators On
For two positive integers m and n, we let Pn be the open convex cone in R consisting of positive definite n × n real symmetric matrices and let R be the set of all m×n real matrices. In this article, we investigate differential operators on the non-reductive manifold Pn × R (m,n) that are invariant under the natural action of the semidirect product group GL(n,R)⋉R on the MinkowskiEuclid space P...
متن کاملDifferentiable Perturbation of Unbounded Operators
If A(t) is a C1,α-curve of unbounded self-adjoint operators with compact resolvents and common domain of definition, then the eigenvalues can be parameterized C1 in t. If A is C∞ then the eigenvalues can be parameterized twice differentiable. Theorem. Let t 7→ A(t) for t ∈ R be a curve of unbounded self-adjoint operators in a Hilbert space with common domain of definition and with compact resol...
