[Banach] Abstract of a paper by Eugenio Hernandez

This is an announcement for the paper "Lebesgue-Type inequalities for quasi-greedy bases" by Eugenio Hernandez.

Abstract: We show that for quasi-greedy bases in real Banach spaces the error of the thresholding greedy algorithm of order N is bounded by the best N-term error of approximation times a constant which depends on the democracy functions and the quasi-greedy constant of the basis.
