Spectral phase transition for a class of power-like Jacobi matrices

In this paper we discuss the spectral properties of a class of Jacobi operators defined by An = n a + Cn and qn = — 2na + bn, where (en) and (bn) are real two-periodic sequences. From the asymptotic behavior of the solutions of the generalized eigenequation, which is in the double root case, a mix...

Tartalmi kivonat:In this paper we discuss the spectral properties of a class of Jacobi operators defined by An = n a + Cn and qn = — 2na + bn, where (en) and (bn) are real two-periodic sequences. From the asymptotic behavior of the solutions of the generalized eigenequation, which is in the double root case, a mixed spectrum is obtained.
