Parseval wavelet frames on Riemannian manifold

Functional Analysis 2020-11-30 v1

Abstract

We construct Parseval wavelet frames in L2(M)L^2(M) for a general Riemannian manifold MM and we show the existence of wavelet unconditional frames in Lp(M)L^p(M) for 1<p<1 < p <\infty. This is made possible thanks to smooth orthogonal projection decomposition of the identity operator on L2(M)L^2(M), which was recently proven by the authors in arXiv:1803.03634. We also show a characterization of Triebel-Lizorkin Fp,qs(M)\mathbf F_{p,q}^s(M) and Besov Bp,qs(M)\mathbf B_{p,q}^s(M) spaces on compact manifolds in terms of magnitudes of coefficients of Parseval wavelet frames. We achieve this by showing that Hestenes operators are bounded on manifolds MM with bounded geometry.
