Abstract

Motivated by the notion of an ideal introduced by Godefroy et al. (Studia Math. 104 (1993) 13-59), in this article, we introduce and study the notion of an extremely strict ideal. For a Poulsen simplex K, we show that the space of affine continuous functions on K is an extremely strict ideal in the space of continuous functions on K. For injective tensor product spaces, we prove a cancelation theorem for extremely strict ideals. We also exhibit non-reflexive Banach spaces which are not strict ideals in their fourth dual.
