%0 Journal Article %T A Conditional Quasi-greedy Basis of l_1 %A S. J. Dilworth %A David Mitra %J Mathematics %D 2000 %I arXiv %X We 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. %U http://arxiv.org/abs/math/0008101v1
