An invitation to the lifting decomposition

Jul 20. 2023, 15:10 — 15:50

The lifting decomposition associated to a consistent set of half-spaces on a CAT(0) cube complex was introduced in my joint work with Chatterji and Iozzi, extending previous work such as that of Caprace and Sageev. In this talk I will demonstrate the simplicity and utility of this tool. Specifically, I will give lifting decompositions associated to a variety of natural objects one may have on or in a CAT(0) cube complex and discuss theorems that they helped prove.
