ABSTRACT
In this thesis we show the retlexivity of a Banach space, that is spaces embedded in their
biduals.The concept is realized for the case that the canonical embedding into its bidual
is surjective.We characterize u-ideals in Banach spaces having retlexive properties. We
show that u-ideal achieves its norm on closed unit ball and for any retlexive Banach
space X; u-ideal is always a closed ideal. We also show that u-deal contained in
Jacobsonradical is a zero ring.
