DESCRIPTION:Title: A combinatorial/topological approach to nonlinear dynami
 cs with applications to regulatory network dynamics.\n\nAbstract: The clas
 sical theory of nonlinear dynamical system focuses on the existence and st
 ructure of sets of trajectories. Bifurcation theory makes clear that these
  objects can change dramatically with small changes in the nonlinearities.
  Motivated by questions from systems biology\, where neither parameters no
 r nonlinearities are known with any reasonable level of precision\, I will
  discuss a novel approach to dynamics based on a combinatorial representat
 ion of the dynamics and the use of algebraic topological invariants to ide
 ntify lower bounds on the structure. To provide a concrete realization of 
 these techniques I describe work aimed at identifying simple models for th
 e restriction point dynamics in mammalian cells. \n
