 Publication Conference Paper, other Title Periodic Jacobi operator with finitely supported perturbation on the half-lattice Author(s) Date 2010 English abstract We consider the periodic Jacobi operator $J$ with finitely supported perturbations on $\ell^2(\N)$ subject to Dirichlet boundary condition at $n=0$. We classify all states of $J$ and give their properties. We solve the inverse resonance problem (including characterization): we prove that mapping from real perturbations to the associated regularized Jost functions is one-to-one and onto.
