Abstract
AbstractWe prove that if A is a non-separable abelian tracial von Neuman algebra then its free powers A∗n,2≤n≤∞, are mutually non-isomorphic and with trivial fundamental group, $\mathcal{F}(A^{*n})=1$, whenever 2≤n<∞. This settles the non-separable version of the free group factor problem.
