Decay bounds on eigenfunctions and the singular spectrum of unbounded Jacobi matrices

Jan Janas, Serguei Naboko, Günter Stolz

Bounds on the exponential decay of generalized eigenfunctions of bounded and unbounded selfadjoint Jacobi matrices are established. Two cases are considered separately: (i) the cas…
