# A book useful to learn lattices (discrete groups)

Does anyone know a good book about lattices (as subgroups of a vector space $V$)?

In what context and for what purpose? –  Qiaochu Yuan Jun 30 '12 at 16:20
substantially an introduction to this interesting argument. –  Dubious Jun 30 '12 at 16:58
To what interesting argument? –  Qiaochu Yuan Jun 30 '12 at 18:38
The interesting argument is "Lattices" (I'm sorry for my unclear and stupid comment). I know that lattices are closely related to "solid geometry" and I'm courious. –  Dubious Jun 30 '12 at 19:21

These notes of mine on geometry of numbers begin with a section on lattices in Euclidean space. However they are a work in progress and certainly not yet fully satisfactory. Of the references I myself have been consulting for this material, the one I have found most helpful with regard to basic material on lattices is C.L. Siegel's Lectures on the Geometry of Numbers.

these are books about lattices in this sense: en.wikipedia.org/wiki/Lattice_(order) . I need a book about: en.wikipedia.org/wiki/Lattice_(group) –  Dubious Jul 4 '12 at 9:54
