摘要
Let X-1,X-2,... X-n be Banach spaces and psi a continuous convex function with some appropriate conditions on a certain convex subset of R-n. Let (X-1 circle plus X-2 circle plus ... circle plus X-n)(psi) be the direct sum of X-1, X-2, ..., X-n equipped with the associated not m with psi. Then we Live the characterization of smoothness of (X-1 circle plus X-2 circle plus ... circle plus X-n)(psi).
