The quotient space, space by a lattice. This concept plays an important r?le in the discussion of inhomogeneous problems in Chapter XI: but we shall also need it in Chapter VIII as it gives the most natural interpretation of . theorem about the successive minima of a convex body with respect to a lattice.

Automorphs,ently form a group. Many of the point sets of interest in the geometry of numbers, or which occur naturally in problems arising in other branches of number-theory, have a rich group of automorphs which is reflected in the set of .-admissible lattices. Already in the work in which he introduced the n

Theorems of B, and M,n 2..(Λ). In § 2 we shall prove M. theorem and some refinements. We shall not follow M. own proof but deduce his theorem from one of B., which has important applications of its own and which is intuitively practically obvious: if a point set . has volume strictly greater than .(Λ) then it contains t
