Applied Maths Seminar: Upanshu Sharma

Dear all, 

Our upcoming AM seminar is held this Wed 6 September at 1pm in F07 Carslaw Lecture
Theatre 373.  Our speaker is Upanshu Sharma (University of New South Wales).  

Talk details follow below: 

Title: Coarse-graining of Markov chains 

Abstract: Coarse-graining is the procedure of approximating large and complex systems by
simpler and lower-dimensional ones.  It is typically characterised by a mapping which
projects the full state of the system onto a smaller set; this mapping captures the
relevant (often slow) features of the system.  Starting from a continuous-time Markov
chain and such a mapping, I will discuss an effective dynamics which approximates the
true projected Markov chain and present error estimates in relative entropy on the
approximation error.  This talk is based on joint work with Bastian Hilder.
