Streszczenie

We prove that a continuous image of a Radon–Nikodým compact of weight less than ${\bf b}$ is Radon–Nikodým compact. As a Banach space counterpart, subspaces of Asplund generated Banach spaces of density character less than ${\bf b}$ are Asplund generated. In this case, in addition, there exists a subspace of an Asplund generated space which is not Asplund generated and which has density character exactly ${\bf b}$.
