Trace Formulas and Borg-type Theorems for Matrix-Valued Jacobi and Dirac Finite Difference Operators

Abstract

Borg-type uniqueness theorems for matrix-valued Jacobi operators H and supersymmetric Dirac difference operators D are proved. More precisely, assuming reflectionless matrix coefficients A,B in the self-adjoint Jacobi operator H=AS++A-S-+B (with S± the right/left shift operators on the lattice View the MathML source) and the spectrum of H to be a compact interval [E-,E+], E-
