Lattice (group)

（重定向自Point lattice）

In mathematics, especially in geometry and group theory, a lattice in $\mathbb{R}^n$ is a subgroup of $\mathbb{R}^n$ which is isomorphic to $\mathbb{Z}^n$ , and which spans the real vector space $\mathbb{R}^n$ . In other words, for any basis of $\mathbb{R}^n$ , the subgroup of all linear combinations with integer coefficients forms a lattice. A lattice may be viewed as a regular tiling of a space by a primitive cell.
