SUMMARY:Spatially dependent collision rates in the Goldstein-Taylor model 
 (and possibly other spatially inhomogeneous kinetic equations) - Jo Evans 
 (University of Warwick)

DESCRIPTION:This is based on a joint work with Helge Dietert. I will discu
 ss the problem of hypocoercivity when the rate of collisions depends on th
 e spatial variable\, and the connection of this problem to control theory.
  In a recent work with Helge Dietert we have been focussing on the problem
  of finding the spatially dependent jump rate which maximises the rate of 
 convergence to equilibrium. I will discuss our results for the simple Gold
 stein-Taylor model and our hopes for more complicated models. I will try a
 nd end with discussing a number of out unanswered problems\, so come along
  and so you can tell me what you think the answers are!
