DESCRIPTION:Abstract: In this talk I will introduce a discrete model of gr
 avity \npreserving constraints of the Einstein’s equations. This model i
 s based \non matrix geometry developed to discretize infinite-dimensional
  systems \nsuch as Eulerian fluid  magnetohydrody- namics and complex fl
 uids. In \nthese cases we’ve been able to discretize underlying symmetri
 es and \nvariational principles to construct numerical schemes preserving 
 \ngeometric structures of the equations. I will discuss how to extend \nth
 ese methods using ideas of noncommutative geometry in order to to \ndiscre
 tize the Einstein’s equations while preserving its symmetries.
