... Furstenberg’s proof to show that a class of domains R has infinitely many nonassociate irreducibles, by means of an adic topology on R. However adic topologies — while arising naturally in commutative algebra — are not so interesting as topologies: cf. §3.3. In [Go59], S.W. Golomb defined a new topo ...
