This paper gives an elementary, self-contained proof that a ΓΏnite product of ΓΏnitely generated subgroups of a free group is closed in the proΓΏnite topology. The proof uses inverse automata (graph immersions) and inverse monoid theory. Generalizations are given to other topologies. In particular, we

Let H and K be quasiconvex subgroups of a negatively curved locally extended Ε½ . residually finite LERF group G. It is shown that if H is malnormal in G, then the double coset KH is closed in the profinite topology of G. In particular, this is true if G is the fundamental group of an atoroidal LERF
