This is an announcement for the paper "Some representation theorem for nonreflexive Banach space ultrapowers under the Continuum Hypothesis" by Piotr Wilczek. Abstract: In this paper it will be shown that assuming the Continuum Hypothesis (CH) every nonreflexive Banach space ultrapower is isometrically isomorphic to the space of continuous, bounded and real-valued functions on the Parovicenko space. This Representation Theorem will be helpful in proving some facts from geometry and topology of nonreflexive Banach space ultrapowers.
