Learning outcomes

The goal of this course is to provide the mathematical foundations needed for understanding the body of recent research connecting (1) analysis on metric spaces and (2) geometric group theory.

Description of prerequisites

Introductory courses in analysis and topology (MATS213 Metric spaces, MATA255 Vector analysis 1 and
MATA256 Vector analysis 2)
