This is an up-to-date survey of selected topics in harmonic analysis in the complex domain.
After a brief description of the role of singular integrals, Riesz transforms, holomorphic Hardy spaces, maximal functions, BMO, the author gets to the more recent results in several variables that are due mainly to E. Stein, G. Weiss, J. P. d’Angelo, J. McNeal, S. G. Krantz and co- workers. This involves homogeneous type structures on the (smooth) boundary of domains in \(\mathbb{C}^n\) and brings in the complex geometry (Levi form, stratification of pseudoconvex points, etc.) on the boundary, which determines the shape of the canonical balls there. Here atomic Hardy spaces can be defined and studied. Several recent theorems are stated, but there are no proofs and many essential details are necessarily left out.
