Explore the fundamental concepts of CAT(0) cube complexes in this 55-minute lecture delivered by Nir Lazarovich as part of the Workshop on Cube Complexes and Combinatorial Geometry. Gain insights into this important mathematical topic through an introductory minicourse that lays the groundwork for understanding the geometric and combinatorial properties of these structures. Delve into the core principles and applications of CAT(0) cube complexes, setting the stage for further exploration in subsequent sessions of the workshop.
