Abstract
We show that any countable subgroup of the multiplicative group of positive real numbers can be realized as the fundamental group F(A) of a separable simple unital C⁎-algebra A with unique trace. Furthermore for any fixed countable subgroup G of , there exist uncountably many mutually nonisomorphic such algebras A with G=F(A).
