Calderón-Zygmund Capacities and Operators on Nonhomogeneous Spaces

A co-publication of the AMS and CBMS
Singular integral operators play a central role in modern harmonic
analysis. Simplest examples of singular kernels are given by
Calderón–Zygmund kernels. Many important properties of singular
integrals have been thoroughly studied for Calderón–Zygmund
operators.
In the 1980's and early 1990's, Coifman, Weiss, and Christ noticed that the
theory of Calderón–Zygmund operators can be generalized from
Euclidean spaces to spaces of homogeneous type. The purpose of this book is to
make the reader believe that homogeneity (previously considered as a
cornerstone of the theory) is not needed. This claim is illustrated by
presenting two harmonic analysis problems famous for their difficulty.
The first problem treats semiadditivity of analytic and Lipschitz harmonic
capacities. The volume presents the first self-contained and unified proof of
the semiadditivity of these capacities. The book details Tolsa's solution of
Painlevé's and Vitushkin's problems and explains why these are problems
of the theory of Calderón–Zygmund operators on nonhomogeneous
spaces. The exposition is not dimension-specific, which allows the author to
treat Lipschitz harmonic capacity and analytic capacity at the same time.
The second problem considered in the volume is a two-weight estimate for the
Hilbert transform. This problem recently found important applications in
operator theory, where it is intimately related to spectral theory of small
perturbations of unitary operators.
The book presents a technique that can be helpful in overcoming rather bad
degeneracies (i.e., exponential growth or decay) of underlying measure (volume)
on the space where the singular integral operator is considered. These
situations occur, for example, in boundary value problems for elliptic PDE's in
domains with extremely singular boundaries. Another example involves harmonic
analysis on the boundaries of pseudoconvex domains that goes beyond the scope
of Carnot-Carathéodory spaces.
The book is suitable for graduate students and research mathematicians
interested in harmonic analysis.
