Advancing research. Creating connections. A description of the automorphism groups of even positive-definite unimodular dimensional lattices is given. This is a preview of subscription content, log in Cited by: 2. In this paper, we give a simple construction method of positive definite unimodular lattices with trivial automorphism groups (i.e.,?the tri-diagonal matrix method), and obtain odd positive. Letp>13 be a prime congruent to 1 modulo 4. Let G be the genus of a quaternary even positive definite Z-lattice of discriminant 4pwhose 2-adic localization has a proper 2-modular Jordan component.
A recent paper of B. Gross and C. McMullen  deals with the characteristic polynomials of automorphisms of even, unimodular lattices with signature (p, q). In Section 3 of the present paper a.

Leech lattice. In mathematics, the Leech lattice is an even unimodular lattice Λ 24 in dimensional Euclidean space, which is one of the best models for the kissing number problem. It was discovered by John Leech (). It may also have been discovered (but not published) by Ernst Witt in
