Research Talk: An Introduction to Hierarchical Hyperbolicity

Hierarchical hyperbolicity provides a common framework to work with various classes of spaces and groups such as mapping class groups, Teichmueller space, and cubical groups, as well as many fundamental groups of 3-manifolds, Artin groups, etc. I will explain what a hierarchically hyperbolic structure is and try to convey a picture of what a hierarchically hyperbolic space looks like.
