Query: Weak weight-semi-greedy bases   We continue the study of the implication from semi-greedy to almost greedy
Markushevich bases, and improve known results. We also introduce and study the
notion of weak weight-semi-greedy bases - which extends the concepts of weight
semi-greedy and weak semi-greedy bases. In particular, we study conditions
under which such bases are weight almost greedy. Finally, we define weak weight
almost greedy bases, and prove that this natural extension is equivalent to the
concept of weight almost greedy bases.
