This course will be run as a working group consisting of faculty, post-docs, and graduate students. The topics that will be covered include: integral equation formulations of PDEs, numerical methods for singular quadrature, fast algorithms, and optimization methods. The material will range from standard/introductory level to recent research results, and will be presented via paper discussion, lectures by faculty, and reports on recent research progress by graduate students and post-docs (roughly 1/3 time spent on each). Application areas will include fluid mechanics, magnetofluid dynamics (plasma physics), and electromagnetics. The working group will be advertised and open to all graduate students, pending approval of the faculty organizers.
There is no textbook for this course. Supplemental references will be suggested as necessary.
Relevant code examples will be posted on gitlab.com/oneilm/sp19-math2840.
