Homogeneous Besov and Triebel–Lizorkin spaces associated to non-negative self-adjoint operators

Abstract

Homogeneous Besov and Triebel–Lizorkin spaces with complete set of indices are introduced in the general setting of a doubling metric measure space in the presence of a non-negative self-adjoint operator whose heat kernel has Gaussian localization and the Markov property. The main step in this theory is the development of distributions modulo generalized polynomials. Some basic properties of the general homogeneous Besov and Triebel–Lizorkin spaces are established, in particular, a discrete (frame) decomposition of these spaces is obtained. © 2016 Elsevier Inc.
