    On the Moduli of Convexity

  • Original language description

    It is known that, given a Banach space (X,// . //), the modulus of convexity associated to this space .delta.x is a non-negative function, non-decreasing, bounded above by the modulus of convexity of any Hilbert space and satisfies the equation .........for every 0 < .xi. <.mu. < 2, where L > 0 is a constant. We show that, given a function f satisfying these properties then, there exists a Banach space in such a way its modulus of convexity is equivalent to f, in Figiel´s sense. Moreover this Banach space can be taken to be two-dimensional.

    O modulu convexity

  • Czech description

    Pro libovolně zvolenou funkci modulu je ukázáno, že Hilbertův prostor je možno renormovat tak, aby tato funkce byla ekvivalentní modulu rotundity nové renormace. Důsledkem je též odhalení chyby v klasickém článku Asplunda z Acta Mathematica a řešení otázky Godefroy a Zizlera.
