On the structure of the diffusion distance induced by the fractional dyadic Laplacian
María Florencia Acosta, Hugo Aimar, Ivana Gómez +1
In this note we explore the structure of the diffusion metric of Coifman-Lafon determined by fractional dyadic Laplacians. The main result is that, for each , the diffusion…
