Abstract

Let X X and Y Y be metric spaces and let ϕ : C p ( X ) C p ( Y ) \phi :{C_p}(X) \to {C_p}(Y) (resp. ϕ : C p ( X ) C p ( Y ) \phi :C_p^\ast (X) \to C_p^\ast (Y) ) be a continuous linear surjection. We prove that Y Y is completely metrizable whenever X X is. As a corollary we obtain that complete metrizability is preserved by l p {l_p} (resp. l p l_p^\ast -equivalence) in the class of all metric spaces. This solves Problem 35 in [2] (raised by Arhangel’skiĭ).
