I added a bit to lattice in a vector space, notably: generalizing to the case of a discrete cocompact subgroup of a general locally compact abelian group. In so doing, I decided to retitle it lattice (discrete subgroup), which is how Wikipedia solves the nomenclature problem.
]]>This was long overdue: I have created a page lattice (disambiguation) and added corresponding warnings on terminology to the relevant entries.
In the course of this I have created stubs for lattice in a vector space, integral lattice and modular integral lattice.
