Lattices in $$\mathbb {R}^n\rtimes \textrm{SL}_2(\mathbb {R})$$
We determine the existence of cocompact lattices in groups of the form \(\textrm{V}\rtimes \textrm{SL}_2(\mathbb {R})\), where \(\textrm{V}\) is a finite dimensional real representation of \(\textrm{SL}_2(\mathbb {R})\). It turns out that the answer depends on the parity of \(\dim (\textrm{V})\) when the representation is irreducible.
