24. SINGULAR INTEGRAL OPERATORS WITH PIECEWISE CONTINUOUS COEFFICIENTS AND THEIR SYMBOLS

Author

I C Gohberg and N J Krupnik

Subjects
Singular integral operators of convolution type, Mathematical analysis, Microlocal analysis, General Medicine, Spectral theorem, Operator theory, Singular integral, Compact operator, Operator norm, Fourier integral operator, Mathematics
Abstract

The algebra generated by one-dimensional singular integral operators with piecewise continuous coefficients is studied. Operators acting on the space Lp with a weight are considered. The contour is assumed to consist of closed and open arcs. The structure of the symbols of the operators considered is elucidated. It is found that the symbol is a matrix-function of the second order depending both on p and on the weight. Criteria that the operator be Fredholm and a formula for its index are established.

32. AN OPERATOR GENERALIZATION OF THE LOGARITHMIC RESIDUE THEOREM AND THE THEOREM OF ROUCHÉ

Author

I C Gohberg and E I Sigal

Subjects
Discrete mathematics, Factor theorem, Picard–Lindelöf theorem, Fundamental theorem, Factorization, Mathematics::Complex Variables, General Mathematics, Residue theorem, No-go theorem, Argument principle, Mathematics, Logarithmic form
Abstract

We obtain the operator generalization of the theorem on the logarithmic residue for meromorphic operator-functions. The proof of the generalization is based on a theorem concerning a special factorization of a meromorphic operator-function at a point. This theorem also allows us to generalize, to the case of meromorphic operator-functions, the formula of M. V. Keldys for the principal part of the resolvent as well as several other theorems.A definition is given for the multiplicity of a pole for a meromorphic operator-function. The basic properties of the multiplicity of a pole are proved, and also a generalization of the Rouche theorem.Bibliography: 16 items.
