Let ∧ be a lattice in Euclidean n-space, that is, ∧ is a set of points ε1a1 + … + εnan where a1… , an are linearly independent vectors and the ε run over all integers. Let μ denote the Lebesgue measure. A closed convex set F is called a fundamental region for ∧ if the sets F + x (x ∈∧) cover the whole space without overlapping; that is, if F0 is the interior of F, and 0 ≠ x ∈ ∧, then F0(F0 + x) = ϕ.
