A Characterization of Positive Self-adjoint Extensions and Its Application to Ordinary Differential Operators
A new characterization of the positive self-adjoint extensions of symmetric operators, T0, is presented, which is based on the Friedrichs extension of T0, a direct sum decomposition of domain of the adjoint T ∗ 0 and the boundary mapping of T ∗ 0 . In applying this result to ordinary differential equations, we characterize all positive self-adjoint extensions of symmetric regular differential o...
متن کاملFactorization of self-adjoint ordinary differential equations
Keyword: Factorization method Self-adjoint differential equations Eigenvalue problems This paper deals with the factorization of self-adjoint differential operators Lð2nÞ 1⁄4 1 q d n dx qb d n dx , and their spectral type differential equations. Sufficient conditions of factorization are reported. A large class of differential operators and equations that can be factorized is obtained. The fact...
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 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...
متن کاملCommuting Self-Adjoint Extensions of Symmetric Operators Defined from the Partial Derivatives
We consider the problem of finding commuting self-adjoint extensions of the partial derivatives { 1 i ∂ ∂xj : j = 1, . . . , d } with domain C c (Ω) where the self-adjointness is defined relative to L (Ω), and Ω is a given open subset of R. The measure on Ω is Lebesgue measure on R restricted to Ω. The problem originates with I.E. Segal and B. Fuglede, and is difficult in general. In this paper...
