Borg-Type Theorems for Matrix-Valued Schrödinger Operators
Steve Clark, Fritz Gesztesy, Helge Holden +1
A Borg-type uniqueness theorem for matrix-valued Schrödinger operators is proved. More precisely, assuming a reflectionless potential matrix and spectrum a half-line ,…

Weyl-Titchmarsh M-Function Asymptotics for Matrix-Valued Schrödinger Operators
Steve Clark, Fritz Gesztesy
We explicitly determine the high-energy asymptotics for Weyl-Titchmarsh matrices associated with general matrix-valued Schrödinger operators on a half-line.
