Strong Tits alternative for Out($F_n$)

By Vincent Guirardel

We prove that any subgroup of Out($F_N$) is either virtually abelian or has a finite index subgroup with an acylindrically hyperbolic quotient. In particular, every subgroup of Out($F_N$) is either virtually abelian or SQ-universal. This is a joint work with Camille Horbez.
