Mathematics Colloquium: A/Prof Stephen Tillman
Topic: Complexity of 3-Manifolds
In this talk, I will describe key aspects of the mathematical study of 3-dimensional spaces, highlighting differences and similarities with the study of surfaces and higher dimensional spaces. I will then explain different measures of complexity of such spaces, and describe some bounds on the complexity. This connects combinatorics, algebra, geometry, and topology.
