Friedrichs extension of singular symmetric differential operators
نویسندگان
چکیده
For singular even order symmetric differential operators we find the matrices which determine all extensions of minimal operator. And for each these is bounded below boundary condition its Friedrichs extension. The regular problems are and thus one has a extension See also https://ejde.math.txstate.edu/special/02/b1/abstr.html

Unbounded operators, Friedrichs’ extension theorem
Explicit naming of the domain of an unbounded operator is often suppressed, instead writing T1 ⊂ T2 when T2 is an extension of T1, in the sense that the domain of T2 contains that of T1, and the restriction of T2 to the domain of T1 agrees with T1. An operator T ′, D′ is a sub-adjoint to an operator T,D when 〈Tv,w〉 = 〈v, T ′w〉 (for v ∈ D, w ∈ D′) For D dense, for given D′ there is at most one T...
متن کاملUnbounded operators and the Friedrichs extension
In this note, by A ⊂ B, I mean that A is contained in B, and it may be that A = B; usually I write this by A ⊆ B, but A ⊂ B fits with the usual notation for saying that an operator is an extension of another. In this note, unless we say otherwise H denotes a Hilbert space over C, and we do not presume H to be separable. We shall write the inner product 〈·, ·〉 on H as conjugate linear in the sec...
متن کاملFriedrichs Model Operators of Absolute Type with One Singular Point
Problems of existence of the singular spectrum on the continuous spectrum emerges in some mathematical aspects of quantum scattering theory and quantum solid physics. In the latter field, this phenomenon results from physical effects such as the Anderson transitions in dielectrics. In the study of this problem, selfadjoint Friedrichs model operators play an important part and constitute quite a...

متن کاملConformally Covariant Differential Operators: Symmetric Tensor Fields
We extend previous work on conformally covariant differential operators to consider the case of second order operators acting on symmetric traceless tensor fields. The corresponding flat space Green function is explicitly constructed and shown to be in accord with the requirements of conformal invariance. PACS: 03.70.+k; 11.10.Kk; 11.25.Hf; 11.30.Ly
