課程概述 |
The following topics will be covered:
(a) Proof of h-cobordism theorem and generalized Poincare conjecture for dim 5 or higher.
(b) Discussions on dim 4, including an introduction to Donaldson/Freedman’s results.
(c) Cobordism theory, characteristic classes and exotic differentiable structures.
(d) C.T.C Wall’s theory on surgery in dimension 6 and its role in classification of Calabi—Yau 3-folds. |
課程目標 |
The course intends to provide a basic training in differentiable topology and an introduction to classification theory of higher dimensional manifolds. After going through some details of famous historic advances in general higher dimensions theories, notably characteristic classes, h-cobordism and discoveries of exotic differentiable structures, I will give an introduction to the 4-dimensional story via Donaldson’s theory.
In the second half of the course, I will focus on C.T.C. Wall’s theory on surgery and its application to the classification of 6 dimensional manifolds with almost complex structures. The main goal is to understand the possible obstructions to relate two higher dimensional manifolds of the same dimension and with vanishing first Chern class. The missing details in the class will be assigned as final report topics. |
課程要求 |
Students are required to have basic knowledge in manifolds and topology as in
[1] Differential geometry on manifolds in the level of Warner (GTM 94), Do Carmo (Riemannian geometry), or chapter 1 to 5 in my 2020 graduate course (lectures notes available in my course page).
[2] Algebraic topology in the level of Vick: Homology Theory, or Hatcher: Algebraic Topology.
