• Resumen

  • We prove that a large class of nonamenable almost periodic type III1 factors M, including all McDuff factors that tensorially absorb R∞ and all free Araki–Woods factors, satisfy Haagerup–Størmer’s conjecture (1988): any pointwise inner automorphism of M is the composition of an inner and a modular automorphism
