Singular Series and Singular Integrals

1991
For a given \(\wp \), let p be the rational prime contained in \(\wp \), and let b, e, f denote the integers such that $$ {\wp ^e}\parallel p, {\text{ }}{p^b}\parallel k{\text{ }}\operatorname{and} {\text{ }}N\left( \wp \right) = {p^f}. $$

SINGULAR INTEGRAL OPERATORS AND SINGULAR QUADRATURE OPERATORS ASSOCIATED WITH SINGULAR INTEGRAL EQUATIONS

Acta Mathematica Scientia, 1998
Abstract In this paper, the author discusses some singular integral operators, singular quadrature operators and discretization matrices associated with singular integral equations with Cauchy kernels, and obtain some useful properties for them. These results improve both the classical theory of singular integral equation and the classical theory of ...

On singular integrals

2011
§ 1. In these lectures I present some of the results obtained jointly with A. P. Calderon during the last few years. Not all the results stated here are accompanied by proofs, and for additional details the reader is referred to original papers (**).
