Query: Compactification l-adique de R   We construct a compact topological group Rl which contains both the real
additive group R and the l-adic one Ql (for a given prime number l) as dense
subgroups; thus we study some of its properties. This construction gives an
arithmetic description of the so-called l-adic solenoid classically defined in
terms of foliations.
