Two-Dimensional Töplitz Operators with Measurable Symbols
L. I. Sazonov Rostov State University
Abstract:
For the complete algebra of two-dimensional Töplitz operators with measurable bounded symbols, we establish conditions necessary for the Fredholm property of the operators and prove results on the separation of singularities of the symbols. As a corollary, conditions sufficient for the Fredholm property are established for operators with symbols satisfying local conditions of sectorial type.
