In this thesis we study different variations of sampling inequalities. First,mirroring a result in [56], we give the conditions for sampling-like inequalities for Besov functions on compact Riemannian manifolds and spaces of homogeneous type. The techniques used to prove these results are based on the decomposition of smooth functions into wavelets available in both of these settings. Further, as in the euclidean case, this characterization through a wavelet expansion allows us to deepen the study of Besov spaces, obtaining a trace theorem and results about their local regularity (inspired in the strategies developed in [21, 54]). Finally we shift to work within the classic setting of sampling theory but changing the way samples are taken: ...
