On the Riesz basis property of root vectors system for $2 \times 2$ Dirac type operators

Anton A. Lunyov, Mark M. Malamud

The paper is concerned with the Riesz basis property of a boundary value problem associated in $L^{2} [0, 1] \otimes C^{2}$ with the following $2 \times 2$ Dirac type equation $…

Weyl function of a Hermitian operator and its connection with characteristic function

Vladimir Derkach, Mark Malamud

Let $A$ be a densely defined symmetric operator with equal deficiency indices in a Hilbert space. We introduce the notion of a Weyl function $M (z)$ of $A$ corresponding to an ordin…
