This is the second semester of a course on methods of applied mathematics. It is open to mathematics, science, engineering, and finance students. It is suitable to prepare graduate students for the Applied Mathematics Preliminary Exam in mathematics and the Area A Preliminary Exam in CAM.
Preliminaries (topology and Lebesgue integration)
The Fourier Transform (3 weeks)
The Schwartz space and tempered distributions.
The Fourier transform.
The Plancherel Theorem.
Fundamental solutions of PDE's.
Sobolev spaces (3 weeks)
The Trace Theorem.
Variational Boundary Value Problems (BVP) (3 weeks)
Weak solutions to elliptic BVP's.
Differential Calculus in Banach Spaces and Calculus of Variations (4 weeks)
The Frechet derivatives.
The Chain Rule and Mean Value Theorems.
Higher order derivatives and Taylor's Theorem.
Banach's Contraction Mapping Theorem and Newton's Method.
Inverse and Implicit Function Theorems, and applications to nonlinear functional equations.
Extremum problems, Lagrange multipliers, and problems with constraints.
The Euler-Lagrange equation.
Applications to classical mechanics and geometry.
