Watch a 56-minute conference talk from the Instituto de Matemática Pura e Aplicada where Genevieve Walsh from Tufts University explores right-angled Coxeter groups which are virtually 3-pseudomanifolds. Part of a larger conference on hyperbolic geometry and hyperbolic group theory, this presentation contributes to discussions on recent developments in the field alongside other topics covered by distinguished speakers from institutions worldwide. The conference, organized in partnership with the Clay Mathematics Institute and the NSF, was followed by a workshop aimed at graduate students featuring in-depth introductions to key topics through minicourses led by expert mathematicians.
