Description
According a recent result due to the authors of this talk, both multiple Rademacher system and Rademacher chaos possess the property of random unconditional convergence in $L_\infty$. This fact combined with some novel connections between $L_\infty$-norms of linear combinations of elements of these systems and some special norms of matrices of their coefficients allows us to establish sharp two-sided estimates for the discrepancy of weighted graphs and hypergraphs. Some of these results extend the classical theorems proved by Erdös and Spencer for the unweighted case.
