    Smooth noncompact operators from C(K), K

  • Original language description

    Let K be a scattered compact. We prove that if there exists an operator from the unit ball of C(K) into a Banach space X, which has uniformly continuous derivative, and whose range is noncompact, the X* contains a complemented copy of l1. This improves classical theorems of Pelczynski.

    Hladké nekompaktní operátory z C(K), K

  • Czech description

    NechtˇK je disperzní kompakt. Pokud existuje operátor z jednotkové koule C(K) do Banachova prostoru X, který je nekompaktní a který má uniformně spojitou derivaci, pak X* obsahuje l1. Výsledek zobecňuje klasické výsledky Pelczynského.
