Yang Liu, Zhejiang Normal University, China, and IPFW Visiting Researcher, Controllability, Stabilization, and Synchronization Problems on Boolean Control Networks.

  • June 3.  Poster: PDF
  • Abstract: In this talk, we will introduce the semi-tensor product of matrices, based on which, Boolean networks can be expressed in algebraic forms. Some basic results and new conclusions will be presented on the controllability, stabilization, and partial and complete synchronization of Boolean control networks.

Johann Brauchart, Technische Universität Graz, Austria, Covering, Separation, and Discrepancy for Random Points on the Sphere.

  • May 27. Poster: PDF
  • Abstract: An algorithm based on point evaluations is regarded to be better if it can beat the average case that uses random points. We look into, in particular, three statistics: the "biggest holes" measured by the covering radius, the "closest distances" measured by the least distance, and the "irregularity" of a point set measured by the discrepancy with respect to a family of given test sets (geometric approach) or test functions (analytic approach). We present results regarding the distribution of holes and distances of random and selected deterministic point sets on the unit sphere of dimension >=1. This talk is based on joint work with Josef Dick, Ed Saff, Ian Sloan, Yuguang Wang, and Rob Womersley.
