Course description:

The combinatorial geometry and topology of 3-manifolds and aspherical 4-manifolds will be developed. With a fixed triangulation, hypersurfaces can be represented in normal or almost normal form. The theory of sweepouts will be described, which is a form of Morse theory for hypersurfaces.

Haken n-manifolds will be explored and it will be shown that they are abundant in dimension 4. Haken cobordism itheory n dimension 4 will be computed.

 

Prerequisite:

Beginning courses in algebraic topology, differential topology, differential geometry would be very helpful.
