A Conditional Quasi-greedy Basis of l

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/59726We show that the Lindenstrauss basic sequence in l_1 may be used to construct a conditional quasi-greedy basis of l_1, thus answering a question of Wojtaszczyk. We further show that the sequence of coefficient functionals for this basis is not quasi-greedy.LaTex, 7 pagesFunctional Analysis46B04A Conditional Quasi-greedy Basis of l_1text
