Shells of selfdual lattices viewed as spherical designs

Combinatorics 2007-05-23 v1

Abstract

We find out for which tt shells of selfdual lattices and of theirs shadows are spherical tt-designs. The method uses theta series of lattices, which are modular forms. We analyse fully cubic and Witt lattices, as well as all selfdual lattices of rank at most 24.
