Abstract

By utilizing an irreducible inclusion of type IIIq2 factors coming from a free-product type action of the quantum group SUq(2), we show that the free group factor L(double-struck F sign) possesses irreducible subfactors of arbitrary index > 4. Combined with earlier results of Radulescu, this shows that L (double-struck F sign) has irreducible subfactors with any index value in {4cos2(π/n): n ≧ 3} ∪ [4, + ∞).
