Midwest cousins of Barnes-Wall lattices
Given a rational lattice and suitable set of linear transformations, we construct a cousin lattice. Sufficient conditions are given for integrality, evenness and unimodularity. When the input is a Barnes-Wall lattice, we get multi-parameter series of cousins. There is a subseries consisting of unimodular lattices which have ranks 2d−1 ± 2d−k−1, for odd integers d ≥ 3 and integers k = 1, 2, · · ...
متن کاملA Simple Construction for the Barnes-Wall Lattices
A certain family of orthogonal groups (called “Clifford groups” by G. E. Wall) has arisen in a variety of different contexts in recent years. These groups have a simple definition as the automorphism groups of certain generalized Barnes-Wall lattices. This leads to an especially simple construction for the usual Barnes-Wall lattices. {This is based on the third author’s talk at the Forney-Fest,...
متن کاملCertain Lattice Neighboring from Barnes-wall Lattice and Laminated Lattices
We give classifications of integral lattices which include the Barnes-Wall lattice BW16 or laminated lattices of dimension 1 6 d 6 8 and of minimum 4. Also, we give certain lattice neighboring from each lattice. Furthermore, we study spherical designs and the other properties.
متن کاملFew-cosine spherical codes and Barnes-Wall lattices
Using Barnes-Wall lattices and 1-cocycles on finite groups of monomial matrices, we give a procedure to construct tricosine spherical codes. This was inspired by a 14-dimensional code which Ballinger, Cohn, Giansiracusa and Morris discovered in studies of the universally optimal property. It has 64 vectors and cosines −37 ,− 1 7 , 1 7 . We construct the Optimism Code, a 4-cosine spherical code ...
متن کاملConstraints and the E 10 Coset Model
We continue the study of the one-dimensional E10 coset model (massless spinning particle motion on E10/K(E10)) whose dynamics at low levels is known to coincide with the equations of motion of maximal supergravity theories in appropriate truncations. We show that the coset dynamics (truncated at levels l ≤ 3) can be consistently restricted by requiring the vanishing of a set of constraints whic...
