MA185

This summer I will be the instructor for MA185, otherwise known as complex analysis. The textbook is the most recent edition of Churchill & Brown's Complex Variables and Applications. Regardless of what nonsense you might encounter within the online schedule of classes, we will meet Monday through Thursday, from 8am to 10am, in 3102 Etcheverry.


MA185 Schedule

NOTE: Final exam review office hours will be held Wednesday, 8/13, from approximately 10:30 - 5:00, in 891 Evans.

Practice final, choose 4 problems to do for HW10, due Wed. 8/13

List of theorems, to appear on the exam

NOTE: I have been carrying around a folder full of uncollected HW's that has now reached unreasonable proportions. If you have not gotten any of HW1-7 back, and you would like it back, stop by my office.

7/31 - Midterm #2

8/4 - These last two weeks will be a plethora of results that follow from our extensive classification of the nature of holomorphic functions, their singularities, residues, etc. Specifically, today we finished the behavior of functions near an isolated singularity (last section of Ch. 6), culminating in the Casorati-Weirstrass theorem. We started using complex integral techniques to derive real valued results (beginning of Ch. 7).

8/5 - Finish Jordan's lemma. Continue integral techniques, over possibly more sophisticated contours ("indented paths"), and considering functions involving branch cuts, sines, cosines, etc.

8/6 - Conclude integral techniques. Start on the argument principle and Rouche's theorem.

8/7 - Rouche's theorem implies the open mapping theorem. Possibly continue on to the Schwartz lemma, definitely throw out some ample hints for HW9.

8/11 - Use the Schwartz lemma to characterize the bijective analytic maps from the open unit disk to itself, and then move on to some practice problems. Specifically, we will review the behavior near a removable singularity, Rouche's theorem, and Morera's theorem.

8/12 - Practice problems involving the Schwartz lemma, Liouville's theorem, Rouche's theorem, and singularities.

8/13 - Review practice final.

8/14 - Final exam

Research Interests

My two primary areas of interest are in noncommutative geometry, pioneered by Alain Connes, and in chainlet geometry, pioneered by my advisor, Jenny Harrison. Vaguely speaking, I aspire to use these "modern" theories to derive new "traditional" results.
