Schrödinger-Operatoren für Teilchen mit Spin. A. Wesentliche Selbstadjungiertheit. (Schrödinger operators for particles with spin. A. Essential selfadjointness). (German) Zbl 0646.35016

In dem komplexen Hilbert-Raum \({\mathcal H}=L_ 2({\mathbb{R}}^ 3)\otimes {\mathbb{C}}^ 2\) betrachten wir den Operator \[ S=\{(\frac{1}{i}\frac{\partial}{\partial \vec x}+\vec a)^ 2+U\}\otimes \sigma_ 0+{\vec \eta}+{\vec \sigma}+({\vec \xi}\times \frac{1}{i}\frac{\partial}{\partial \vec x})\cdot {\vec \sigma},\quad {\mathcal D}_ S={\mathcal K}^{(\infty)}({\mathbb{R}}^ 3)\otimes {\mathbb{C}}^ 2). \] Es wird gezeigt, daß S wesentlich selbstadjungiert ist. Eine Zusammenstellung einiger wichtiger Aussagen findet man in Kapitel 4.
