Characterizations of almost greedy and partially greedy bases

Published 17 May 2018 in math.FA | (1805.06778v1)

Abstract: We shall present new characterizations of partially greedy and almost greedy bases. A new class of basis (which we call reverse partially greedy basis) arises naturally from these characterizations of partially greedy bases. We also give characterizations for $1$-partially greedy and $1$-reverse partially greedy bases.
