Abstract :
Several cardinal inequalities and identities concerning fragmentable and sigma-fragmentable spaces are proven. A cardinal function whose countable value in Banach space corresponds to the notion of a WCD space is studied. Some related cardinal functions and classes of Banach spaces are considered.
