Cerdà, Joan; Hudzik, Henryk; Kamińska, Anna; Mastyło, Mieczysław Geometric properties of symmetric spaces with applications to Orlicz-Lorentz spaces. (English) Zbl 0920.46022 Positivity 2, No. 4, 311-337 (1998). Summary: We deal with the basic convexity properties – rotundity, and uniform, local uniform and full rotundity – for symmetric spaces. A characterization of Orlicz-Lorentz spaces with the Kadec-Klee property for pointwise convergence is given. These results are applied to obtain criteria of convexity properties for Orlicz-Lorentz sequence spaces, and some new proofs of the sufficiency part of criteria for rotundity and uniform rotundity for Orlicz-Lorentz function spaces.
