Two characterizations of the standard unit vector basis of
David Mitra
We show that for a sequence in a Banach space, the property of being stable under large perturbations characterizes the property of being equivalent to the unit vector basis of $l_…

A Conditional Quasi-greedy Basis of l_1
S. J. Dilworth, David Mitra
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 tha…
