Arithmetic Geometry Language

4 (Theorem Gillet-Soule)
n-dimensional real vector space and its inner product         (V, h)
x, y (element) Lambda
h(x, y) (element) Z
Free base of Lambda        {w1, ..., wn}
(h(wi, wj)) (element) GL (n, Z)
Boundary symmetry vertex set      K
6(upper)-n <= #(K (cap) Lambda) / #(K*(cap) Lambda)volh(K) <=(3/2)(upper)n(n!)(upper)2

5 (Lemma)
Boundary symmetry vertex set with inner point
K
(cap)Lambda  generates V.
#(K(cap)Lambda)volh(K*)volh(V/A)<=6(upper)n

(Notice)
5(Lemma) is useful as generation theorem for language.

6 (Lemma)
(V, h, Lambda) is uni-modular.
Saturated sub Z module of Lambda        T
T
(orthogonal) = {x(element)Lambda | for all y(element)T, h(x, y) = 0}
V'
s sub-vector space generated by T    W
W
's orthogonal complement       W(orthogonal)
T(orthogonal) is lattice point set of W(orthogonal).

7 (Notice)
6(Lemma) ideally satisfies language that is constructed by lattice. It is called <lattice language>.
