Recent developments in spectral synthesis for exponential systems and for non-self-adjoint operators

Abstract

We survey recent results concerning the hereditary completeness of some special systems of functions and the spectral synthesis problem for a related class of linear operators. We present a solution of the spectral synthesis problem for systems of exponentials in $L^2(-\pi ,\pi )$. Analogous results are obtained for the systems of reproducing kernels in the de Branges spaces of entire functions. We also apply these results (via a functional model) to the spectral theory of rank one perturbations of compact self-adjoint operators.

This is survey of some recent results by the authors (including arXiv:1112.5551). The paper is to appear in the Proceeding of the conference "Recent Trends in Analysis" (Bordeaux, 31.08.2011-02.09.2011) in honor of Nikolai Nikolski
