Abstract

We study the dimension of "random" Euclidean sections of direct sums of normed spaces. We compare the obtained results with results from [LMS], to show that for the direct sums the standard randomness with respect to the Haar measure on Grassmanian coincides with a much "weaker" randomness of "diagonal" subspaces (Corollary 1.4 and explanation after). We also add some relative information on "phase transition".
