Streszczenie
For every $\alpha <\omega _1$ we establish the existence of a separable Banach space whose Szlenk index is $\omega ^{\alpha \omega +1}$ and which is universal for all separable Banach spaces whose Szlenk index does not exceed $\omega ^{\alpha \omega }$. In order to prove that result we provide an intrinsic characterization of which Banach spaces embed into a space admitting an FDD with Tsirelson type upper estimates.
