The original Weyl-Titchmarsh functions and sectorial Shrödinger L-systems

Sergey Belyi, Eduard Tsekanovskii

In this paper we study the L-system realizations generated by the original Weyl-Titchmarsh functions $m_{α} (z)$ in the case when the minimal symmetric Shrö\-dinger operator in $L_2[\…

On realization of the original Weyl-Titchmarsh functions by Shrödinger L-systems

Sergey Belyi, Eduard Tsekanovskii

We study realizations generated by the original Weyl-Titchmarsh functions $m_{\infty} (z)$ and $m_{α} (z)$ . It is shown that the Herglotz-Nevanlinna functions $(- m_{\infty} (z))$ and $(1/m_…
