Syllabus:  MT 8832  Geometry/Topology IV: Surfaces and branched surfaces in 3-manifolds

Spring 2018

Course Description:
MT8832 is a research-oriented graduate course on Geometry and Topology. Topics for this course vary each year depending on the instructors. Topic this year is 3-manifold topology. I will quickly go cover some basics of 3-manifold topology at the beginning and mostly focus on surfaces, branched surfaces, foliations and laminations in knot exteriors.
