Resumen de Rotundity properties in Calderón-Lozanovskií spaces

Pawel Kolwicz

• We find criteria for strict and uniform convexity of Calderón-Lozanovskií spaces solving problem XII from [3] and generalizing several theorems, which give only the sufficient (or necessity) conditions (see [2], [4]). In particular we obtain the respective criteria for Orlicz-Lorentz spaces which has been proved directly in [1], [5], [6]. We give also applications to Orlicz spaces generated by the composing of Orlicz functions.
