The L-system representation and c-entropy

Sergey Belyi, Konstantin A. Makarov, Eduard Tsekanovskii

Given a symmetric operator $A ˙$ with deficiency indices $(1, 1)$ and its self-adjoint extension $A$ in a Hilbert space $H$ , we construct a (unique) L-system with the m…

Realization of inverse Stieltjes functions $(- m_{α} (z))$ by Schrodinger L-systems

Sergey Belyi, Eduard Tsekanovskii

We study L-system realizations of the original Weyl-Titchmarsh functions $(- m_{α} (z))$ . In the case when the minimal symmetric Schrödinger operator is non-negative, we describe the S…
