Abstract:

We prove a version of sparsification result for multipartite graphs which finds within any multipartite graph with positive pairwise densities, a bounded order subgraph with sufficiently many parts and almost the same pairwise densities. Asan application, we settle a multicolor Turan problem first suggested by Bollobas. This is joint work with Ander Lamaison.
