Constructions of algebraic lattices

Abstract: Abstract. In this work we present constructions of algebraic lattices in Euclidean space with optimal center density in dimensions 2, 3, 4, 6, 8 and 12, which are rotated versions of the lattices n , for n = 2, 3, 4, 6, 8 and K 12 . These algebraic lattices are constructed through twisted canonical homomorphism via ideals of a ring of algebraic integers. 18B35, 94A15, 20H10. Mathematical subject classification:

“…Special algebraic lattice constructions can be used to obtain certain lattice parameters such as packing density and minimum product distance, which are usually difficult to calculate for general lattices in R n . Some constructions and properties of algebraic lattices can be found in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. We quote particularly the paper [8], where full diversity rotated versions of the lattices A 2 , E 6 , E 8 , K 12 and Λ 24 are constructed.…”
