DESCRIPTION:Title: Cubulated relatively hyperbolic groups and virtual speci
 alness.\n\nAbstract: Ian Agol showed that hyperbolic groups acting geometr
 ically on CAT(0) cube complexes are virtually special in the sense of Hagl
 und–Wise\, the last step in the proof of the virtual Haken and virtual fib
 ering conjectures. I will talk about a generalization of this result (also
  obtained independently by Groves and Manning)\, which states that cubulat
 ed relatively hyperbolic groups are virtually special provided the periphe
 ral subgroups are virtually special in a way that is compatible with the c
 ubulation. In particular\, we deduce virtual specialness for cubulated gro
 ups that are hyperbolic relative to virtually abelian groups\, extending W
 ise's results for limit groups and fundamental groups of cusped hyperbolic
  3-manifolds. The main ingredient of the proof is a relative version of Wi
 se's quasi-convex hierarchy theorem\, obtained using recent results by Ein
 stein\, Groves\, and Manning.\n\nLink: https://mcgill.zoom.us/j/9891072624
