Abstract

Let {\mathbf{co}}(v) be a lattice of convex subsets of a vector space v over a totally ordered division ring {\mathbb{F}}. We state that every lattice l can be embedded into {\mathbf{co}}(v), for some space v over {\mathbb{F}}. Furthermore, if l is finite lower bounded, then v can be taken finite-dimensional; in this case l also embeds into a finite lower bounded lattice of the form {\mathbf{co}}(v,\omega)=\{x\cap\omega \mid x\in {\mathbf{co}}(v)\}, for some finite subset \omega of v. This result yields, in particular, a new universal class of finite lower bounded lattices.
