Abstract

In this research announcement we outline the methods used in our recent proof that the Leech lattice is the unique densest lattice in R 24 \mathbb {R}^{24} . Complete details will appear elsewhere, but here we illustrate our techniques by applying them to the case of lattice packings in R 2 \mathbb {R}^2 , and we discuss the obstacles that arise in higher dimensions.
