Limit periodic Jacobi matrices with a prescribed p-adic hull and a singularly continuous spectrum
F. Peherstorfer, A. Volberg, P. Yuditskii
In this work we build a certain machine that allows to construct almost periodic Jacobi matrices with singularly continuous spectrum a prescribed p-adic hull.
Remarks on a paper of Geronimo and Johnson
F. Peherstorfer, P. Yuditskii
We present a point of view on results of the paper of Geronimo and Johnson [Comm. Math, Phys. 193 (1998)] that allow infinitely dimensional generalization up to the case when spect…
On generalized sum rules for Jacobi matrices
F. Nazarov, F. Peherstorfer, A. Volberg +1
This work is in a stream initiated by a paper of Killip and Simon [Ann. of Math. (2003)]. Using methods of Functional Analysis and the classical Szegö Theorem we prove sum rule ide…
Zeros of polynomials orthogonal on several intervals
Franz Peherstorfer
First a formula for the number of zeros of the orthogonal polynomial in the intervals is presented. Then a criteria about the appearance of a zero in a gap is given. Finally a nece…
