The Analyst's Traveling Salesman Problem and Multiresolution Analysis Raanan Schul UCLA We discuss a characterization of sets contained in a curve of finite length. The results discussed are an extension of work by Peter Jones and Kate Okikiolu for sets in $\R^d$, to sets lying in Hilbert space. The charcaterization is done via multiscale geometric analysis and a geometric analouge of the square function. This is an example of a place where one can get rid of `The curse of dimensionality'. Time permitting, we will also mention some results for metric spaces by various people. This talk will be self contained.
