Abstract

A Banach space XX is called subprojective if any of its infinite dimensional subspaces YY contains a further infinite dimensional subspace complemented in XX. This paper is devoted to systematic study of subprojectivity. We examine the stability of subprojectivity of Banach spaces under various operations, such us direct or twisted sums, tensor products, and forming spaces of operators. Along the way, we obtain new classes of subprojective spaces.
