Self-adjoint extensions by additive perturbations

Andrea Posilicano — 2003

Annali della Scuola Normale Superiore di Pisa - Classe di Scienze

Let $A_{𝒩}$ be the symmetric operator given by the restriction of $A$ to $𝒩$ , where $A$ is a self-adjoint operator on the Hilbert space $ℋ$ and $𝒩$ is a linear dense set which is closed with respect to the graph norm on $D (A)$ , the operator domain of $A$ . We show that any self-adjoint extension $A_{Θ}$ of $A_{𝒩}$ such that $D (A_{Θ}) \cap D (A) = 𝒩$ can be additively decomposed by the sum $A_{Θ} = \bar{A} + T_{Θ}$ , where both the operators $\bar{A}$ and $T_{Θ}$ take values in the strong dual of $D (A)$ . The operator $\bar{A}$ is the closed extension of $A$ to the whole $ℋ$ whereas $T_{Θ}$ is explicitly written in terms...
