Topics in Harmonic Analysis Related to the Littlewood-Paley Theory. (AM-63)
Elias M. Stein · Princeton University Press eBooks · 1970
This work deals with an extension of the classical Littlewood-Paley theory in the context of symmetric diffusion semigroups. In this general setting there are applications to a variety of problems, such as those arising in the study of the expansions coming from second order elliptic operators. A review of background material in Lie groups and martingale theory is included to make the monograph more accessible to the student.
