Dear All,

The first NT seminar of the quarter will be Tuesday, 10/4, at 11am, in PDL C-401. 

Our speaker is Seungki Kim, from the University of Cincinnati.

Title: Lattice problems and the Siegel/Rogers integral formula
Abstract: This talk is an introduction to the classical lattice problems of sphere packing and covering in arbitrarily high dimensions, and the Siegel and Rogers integral formula developed in the 1940-50's to study them. They still remain as one of the strongest approaches to the family of such problems, and the records established back then remain unbeaten to this day. I present some past and recent works in the literature, as well as a few works of mine, that are in some sense reflections on the difficulty of these problems.
