WEYL FUNCTION FOR SUM OF OPERATORS TENSOR PRODUCTS

Аннотация:

The boundary triplets approach is applied to the construction of self-adjoint extensions of the operator having the form S = A ⊗ IT + IA ⊗ T where the operator A is symmetric and the operator T is bounded and self-adjoint. The formula for the γ-field and the Weyl function corresponding the the boundary triplet ΠS is obtained in terms of the γ-field and the Weyl function corresponding to the boundary triplet ΠA.
