Families of Equiangular Lines and Lattices
Jacques Martinet · arXiv (Cornell University) · 2024
We construct Euclidean lattices whose sets of minimal vectors support some large equiangular families of lines, using notably reduction modulo~$2$ of lattices. %as considered in \cite{Ma1} and \cite{Ma2}. We also consider some related problems, and answer a question raised by Greaves ([G], Subsection~1.3.2).
