Speaker : Hung-Lin Chiu (National Central University) Title : CR structure on $S^{3}$ Time : 2014-04-25 (Fri) 10:30 - 12:00 Place : Seminar Room 722, Institute of Mathematics (NTU Campus) Abstract: I will talk following the paper "Contact geometry and CR structures on $S^{3}$", by John S. Bland and focus on the action of the contact diffeomorphisms on the CR structures. John S. Bland shows that the contact diffeomorphisms group can be used to place the CR structures in various normal forms and applies these results to the embedding problem.
