## Math 553: Asymptotic Analysis and Perturbation Methods
(Fall 2020) [6863]

Asymptotic analysis and perturbation methods provide powerful techniques in
applied mathematics for obtaining simple analytical forms to reliably
approximate
solutions to complicated problems in a range of different mathematical
settings. This course will cover material on asymptotic expansions, solution
of nonlinear algebraic equations, regular and singular perturbations
problems,
perturbations of matrix eigenvalue problems, asymptotics of integrals -
Fourier and Laplace transforms, and solutions of differential equations -
WKB theory, eigenvalue problems, multiple-scale analysis, boundary layers,
and matched asymptotic expansions.
