Tel Aviv University 
 
Hello everyone,
 
The next colloquium talk will be held on:
 
Monday, 31/12/2012, 12:15, Schreiber 006, Tel Aviv University.
 
Speaker: Fedor Nazarov (Kent State University)
 
Title: The ball is a local minimizer of the optimal lattice
packing density in $R^3$.
 
The abstract is given below. Tea and coffee at 12:00, same room.
 
Hope to see you there. For information about future colloquia, see

Yours,
Yaron

Abstract: We show that every symmetric convex body $K\subset R^3$
sufficiently close to the unit ball admits a lattice packing
whose density is not less than that for the ball and is strictly
larger unless $K$ is an ellipsoid. I hope to be able to present
the full proof. This is a joint work with Yoav Kallus.
