  • A small perturbation method is developed and deployed to the construction of compactly supported frames for Besov and Triebel-Lizorkin in the general setting of Dirichlet space with a doubling measure and local scale-invariant Poincaré inequality. This allows, in particular, to develop compactly supported frames for Besov and Triebel-Lizorkin spaces in the context of Lie groups, Riemannian manifolds, and various other settings. The compactly supported frames are utilized for the development of atomic Hardy spaces $H _ {A}^p$ in the general framework of Dirichlet spaces.
