Polyhedral Products: a Path Between Homotopy Theory and Geometric Group Theory

 05 - 09 Jun 2023

ICMS, Bayes Centre, Edinburgh

Scientific organisers

  • Martin Bendersky, CUNY
  • Jelena Grbić, University of Southampton
  • Ian Leary, University of Southampton
  • Stephen Theriault, University of Southampton

About:

The overall aim of the workshop was to generate research opportunities at the intersection of the homotopy theory and geometric group theory associated to polyhedral products. These two areas have substantial common ground but to date have had only limited interaction. The workshop significantly amplified the existing connections and investigated novel interactions between these two areas.
