Resumen
This article is devoted to the problems of invertibility and Fredholmness of operators in the weighted Wiener algebra acting in the weighted spaces of vector-functions on the lattice (μℤ)n = {x∈ℝn: x = μy,y∈ℤn} for small μ>0. We consider the discrete Schrödinger operators on (μℤ)n as applications and study the relation between the spectra of Schrödinger operators on ℝn and its discrete models on (μℤ)n for small μ>0.
