The asymptotic behavior of the eigenvectors and generalized eigenvectors for the spectral parameter belonging to a gap in the spectrum (or in the essential spectrum) will be considered. The main goal is to discuss the so-called Combes-Thomas-type estimates for (unbounded) Jacobi matrices, generalizing well-known results for the case of continuous Schrodinger operators. We also plan to present some applications of the eigenvector analysis. The presentation is based on joint work with J. Janas and G. Stolz.
