DESCRIPTION:Speaker: Daniel El-Baz\nhosted by Tim Browning\nAbstract: In a 
 2016 paper\, Manfred Einsiedler\, Shahar Mozes\, Nimish Shah and Uri Shapi
 ra used techniques from homogeneous dynamics to establish the equidistribu
 tion of primitive rational points on expanding horospheres in the space of
  unimodular lattices in at least 3 dimensions.Due to the nature of their p
 roof\, relying in particular on Marina Ratner's measure-classification the
 orem\, their result does not come with a quantitative error term. I will d
 iscuss a joint work with Bingrong Huang and Min Lee\, in which we pursue a
 n analytic number-theoretic approach to give a rate of convergence for a s
 pecific horospherical subgroup in any dimension. This extends work of Min 
 Lee and Jens Marklof who dealt with the 3-dimensional case in 2017.
