Half line Titchmarsh-Weyl functions of vector-valued discrete Schrodinger operators
Keshav Raj Acharya, Matt McBride
We show that the half-line functions associated with the vector-valued Schrodinger operators are the elements in the Siegel upper half space. We introduce a metric on the space…

Titchmarsh-Weyl theory for vector valued Schrodinger operators
Keshav Acharya
We develop the Titchmarsh-Weyl theory for vector-valued discrete Schrödinger operators and show that the Weyl functions associated with these operators map complex upper half p…
