Streszczenie
For each ordinal $\alpha <\omega _1$, we prove the existence of a Banach space with a basis and Szlenk index $\omega ^{\alpha +1}$ which is universal for the class of separable Banach spaces with Szlenk index not exceeding $\omega ^\alpha $. Our proof involves developing a characterization of which Banach spaces embed into spaces with an FDD with upper Schreier space estimates.
