Abstract: In this talk we will try to understand a class of subspaces
of $L_p$ first considered by Bourgain, Rosenthal and Schechtman. These
spaces may be defined in two different ways; however for this talk we will
consider the realization through well founded trees. Finally we will see
some glimpses of $L_p$ index theory of this class. This is a joint work with S.Dutta.
