Abstract: We make a systematic study of frames for metric spaces. We prove that every separable metric space admits a metric $${\mathcal {M}}_d$$ M d -frame. Through Lipschitz-free Banach spaces we show that there is a… read more here.

Abstract: Frames provide redundant, stable representations of data which have important applications in signal processing. We introduce a connection between symplectic geometry and frame theory and show that many important classes of frames have natural symplectic… read more here.
