In terms of weak differentiability of norms and algebraic complementation of subspaces, the single-valuedness of the Hahn-Banach continuation is characterized, as well as its linearity as an operator. The connection is established between this contin

A geometrical characteristic of the closure of a sum of subspaces of a Banach space is derived and is subsequently used in the description of systems of translations of spaces having a Chebyshev point.
