Annual Program Seminars

During each Annual Thematic Program, several seminars are offered. Talks will include graduate-level lectures as well as seminars covering various topics related to the theme.

  • Measurable Equidecompositions via Combinatorics and Group Theory

    Oleg Pikhurko, University of Warwick

    Abstract

    Let n>2. We show that every two subsets of S^{n-1} (resp. two bounded subsets of R^n) of the same measure and with non-emtpy interior can be equidecomposed using pieces that are measurable. Joint work with Lukasz Grabowski and Andras Mathe.
  • Spatial Models for Big Networks

    Abstract

    Stochastic models for online social networks are built on the assumption that the vertices create links according to a personal profile. In other words, it is the ‘landscape’ of personal profiles that gives rise to the graph. It is natural to model this hidden information as a placement of the vertices in some metric space, and model the graph formation as a random process where link probability decreases with distance. Link analysis, the extraction of information about the vertices by looking at the graph, is an important tool of network data mining. In graph theory terms, this corresponds to the “inverse problem”: given a graph and a spatial/geometric model, is it possible to retrieve information about metric distance from the graph? I will give an overview of some relevant tools and models, and focus on open questions and new directions of research.
