MTH 628: Advanced Topics in Partial Differential Equations, Winter, 2005

LECTURE: MWF 1500 - 1550 Gilkey Hall 104 CRN 28379
Instructor: R.E. Showalter Kidder 368 show@math.oregonstate.edu

After a review of Lp spaces, we construct and describe the corresponding Sobolev spaces together with the trace map onto boundary values. Existence theorems are established for monotone operators from a Banach space to its dual, and these are applied to resolve quasi-linear elliptic boundary-value-problems. Then we develop the variational theory for rather general convex functions and the corresponding problems associated with the generalized derivative or subgradient .
The prerequisite material for the course consists of some familiarity with Lp spaces and related analysis and either some experience or motivation from differential equations or boundary-value problems. In particular, the preceding MTH 627 course is not a prerequisite.
Prerequisite: MTH 627 or consent of instructor.
Final Exam: Tuesday, March 15, 1200.
Textbook: Monotone Operators in Banach Space and Nonlinear Partial Differential Equations. It is available on-line!
