Prerequisites: Math 104 (analysis), Math 185 (complex analysis), Math 110 (linear algebra). 224A is not a prerequisite.

Syllabus: The course will survey basic theory and practical methods for solving the fundamental problems of mathematical physics. It is intended for graduate students in applied mathematics, physics, engineering or other mathematical sciences. The overall purpose of the course will be to develop non-numerical tools for understanding and approximating solutions of differential equations. A rough outline for 224B is:

• Linear and Nonlinear Waves (KdV, NLS, the inverse scattering method). (refs 1-2)
• Potential theory, integral equations, compact operators. (refs 3.4)
• Euler equations, potential flow, water waves, conformal mapping methods, stability of traveling waves. (refs 5-6)
• Stokes equations, Lam'e equations, weak solutions, Lax-Milgram theorem, Korn's inequality, saddle-point problems, inf-sup conditions. (refs 7-8)
• Semigroup theory, parabolic equations, porous medium equation. (refs 9-10)
• asymptotic behavior of solutions of ordinary differential equations, WKB theory. (refs 11-12)
• asymptotic behavior of integrals, method of steepest descent, method of stationary phase. (ref 12)
• asymptotics behavior of elliptic systems near corners, Mellin transform. (ref 13)
• singular perturbation theory and boundary layer theory. (refs 14-15)
