Let be a finitely generated subgroup of SL (2, ℱ), where ℱ is the ring; of holomorphic functions on the open unit disc Δ. For each point z 0 in Δ we can evaluate all matrix entries of at z 0 , to obtain a subgroup { z 0 } of SL (2, ℂ) and a surjective representation → {z 0 }. If this representation is not faithful, then contains a nontrivial element W such that W evaluated; at z 0 is trivial. But W can evaluate to the identity only on a countable subset) of Δ, and there are only countably many choices for W in Consequently there are at most countably many points z k in Δ such that {z k } is not isomorphic to Δ. Our main result can now be stated as follows.
