Connectivity at Infinity for Right Angled Artin Groups

  title={Connectivity at Infinity for Right Angled Artin Groups},
  author={Noel Brady},
We establish sufficient conditions implying semistability and connectivity at infinity properties for CAT(0) cubical complexes. We use this, along with the geometry of cubical K(π, 1)’s to give a complete description of the higher connectivity at infinity properties of right angled Artin groups. Among other things, this determines which right angled Artin… CONTINUE READING
