Cubical complexes and RAAGs Reading Seminar

Graduate Center CUNY, Spring 2013

About the seminar: This is a reading seminar on Cubical complexes, Right Angled Artin groups (RAAGs) and their applications to group theory and 3-manifolds. We will start by covering some background topics and proceed to read parts of the lecture notes by Daniel Wise (linked below), which is based on his lectures given at the Graduate Center in summer of 2011 (see link below). This seminar is accessible to graduate students and non-experts. Everyone is welcome.
