For a fusion Banach frame for a Banach space , if is a fusion Banach frame for , then is called a fusion bi-Banach frame for . It is proved that if has an atomic decomposition, then also has a fusion bi-Banach frame. Also, a sufficient condition for the existence of a fusion bi-Banach frame is given. Finally, a characterization of fusion bi-Banach frames is given.

In a recent paper by H. X. Cao, J. H. Zhang and Z. B. Xu an -Lipschitz operator from a compact metric space into a Banach space is defined and characterized in a natural way in the sence that is a -Lipschitz operator if and only if for each the mapping is a -Lipschitz function. The Lipschitz operators algebras and are developed here further, and we study their amenability and weak amenability of these algebras. Moreover, we prove an interesting result that and are...

We show that a complex Banach space is weakly Lindelöf determined if and only if the dual unit ball of any equivalent norm is weak* Valdivia compactum. We deduce that a complex Banach space X is weakly Lindelöf determined if and only if any nonseparable Banach space isomorphic to a complemented subspace of X admits a projectional resolution of the identity. These results complete the previous ones on real spaces.
