Subprojective Nakano spaces

Abstract

A Banach space X is subprojective if every infinite-dimensional subspace of X has a subspace which is complemented in X. We prove that separable Nakano sequence spaces l((pn)) are subprojective. Subprojectivity is also characterized in separable Nakano function spaces L-p(.) (0,1) and L-p(.) (0, infinity). (C).
