DESCRIPTION:Speaker: Agnes Backhausz\nhosted by Laszlo Erdös\nAbstract: Th
 e goal of the talk is to give an overview on the basic notions of graph li
 mit theory\, and to present recent results about its applications to the s
 pectral theory of random graphs and random matrices. By identifying contin
 uous limit objects (e.g. L^2 operators) as the limit of convergent graph s
 equences\, graph limit theory is a powerful combination of tools from anal
 ysis\, combinatorics and probability theory. In the first part of the talk
 \, we summarize the notions of local limit of bounded degree graphs\, the 
 limit of dense graph sequences\, and the recently defined notion of action
  convergence\, which works for graphs of intermediate density as well. The
 n we present two applications on the empirical distribution of eigenvector
 s of random regular graphs and random sign matrices. Joint work with Balzs
  Szegedy.
