Regular Two-graphs from the Even Unimodular Lattice E8 + E8
نویسنده
چکیده
This is a revised version of the rst part of 8]. Each two-graph is in one-to-one correspondence with a set of equiangular lines. This implies that a two-graph is represented by a system of vectors of equal odd norm with mutual inner products

Self-Dual Codes over Z4 and Unimodular Lattices: A Survey
By using Construction A modulo 4 the following remarkable unimodular lattices have been constructed: the Gosset lattice E8, the Leech lattice, the 23 Niemeier lattices in dimension 24, the two extremal even unimodular lattices in dimension 32 with an automorphism of order 31, all the extremal unimodular lattices and the odd Leech lattice. In this survey, we review basic facts of life in the Z4 ...
متن کاملEmergence of an Aperiodic Dirichlet Space from the Tetrahedral Units of an Icosahedral Internal Space
We present the emergence of a root system in six dimensions from the tetrahedra of an icosahedral core known as the 20-group (20G) within the framework of Clifford’s geometric algebra. Consequently, we establish a connection between a three-dimensional icosahedral seed, a six-dimensional (6D) Dirichlet quantized host and a higher dimensional lattice structure. The 20G, owing to its icosahedral ...
متن کاملLattices like the Leech lattice
The Leech lattice has many strange properties, discovered by Conway, Parker, and Sloane. For example, it has covering radius √ 2, and the orbits of points at distance at least √ 2 from all lattice points correspond to the Niemeier lattices other than the Leech lattice. (See Conway and Sloane [6, Chaps. 22-28].) Most of the properties of the Leech lattice follow from the fact that it is the Dynk...
متن کاملCounting Enriques Quotients of a K3 Surface
Here TX and ρ(X) are respectively the transcendental lattice and the Picard number of X. U and E8 denote the unique even unimodular lattices of signature (1, 1) and (0, 8) respectively. l(L) of a nondegenerate lattice L is the number of minimal generators of the discriminant group AL = L ∗/L of L. Details on AL are found in [6]. As Keum remarks, the assumption (∗) is needed only for the implica...
متن کاملVirasoro Frames and their Stabilizers for the E8 Lattice type Vertex Operator Algebra
The concept of a framed vertex operator algebra (FVOA) is new (cf. [DGH]). This article contributes to this theory with a full analysis of all Virasoro frame stabilizers in V , the important example of the E8 level 1 affine Kac-Moody VOA, which is isomorphic to the lattice VOA for the root lattice of E8(C). We analyze the frame stabilizers, both as abstract groups and as subgroups of Aut(V ) ∼=...
