Constructions of Dense Lattices over Number Fields
Trends in Computational and Applied Mathematics(2020)
摘要
ABSTRACT In this work, we present constructions of algebraic lattices in Euclidean space with optimal center density in dimensions 2;3;4;5;6;8 and 12, which are rotated versions of the lattices Λn , for n=2,3,4,5,6,8 and K 12. These algebraic lattices are constructed through canonical homomorphism via ℤ-modules of the ring of algebraic integers of a number field.
