The Bethe strip of width m is the cartesian product B Γ— {1, . . . , m}, where B is the Bethe lattice (Cayley tree). We prove that Anderson models on the Bethe strip have "extended states" for small disorder. More precisely, we consider Anderson-like Hamiltonians H Ξ» = 1 2 Ξ” βŠ— 1 + 1 βŠ— A + Ξ»V on a Bet

In this paper the realization problems for the KreΘ‹n-Langer class N ΞΊ of matrixvalued functions are being considered. We found the criterion when a given matrix-valued function from the class N ΞΊ can be realized as linear-fractional transformation of the transfer function of canonical conservative s
