The student is expected to be familiar with the major topics (at the advanced undergraduate, beginning graduate level) in linear algebra, advanced calculus, introductory partial differential equations, and introductory complex variables.

Exam topics may include (but are not limited to):

Dimensional Analysis and Scaling:

Buckingham Pi Theorem, characteristic scales, well-scaled problems. Perturbation Methods and Asymptotic Expansions: asymptotic sequences and series, regular perturbations, Poincare'-Lindstedt method, singular perturbations, boundary layer analysis, WKB approximations, asymptotic expansions of integrals.

Calculus of Variations:

first and second variations, Euler-Lagrange equations, first integrals, isoperimetric problems.

Integral Equations and Green's Functions:

Volterra and Fredholm integral equations, degenerate kernels, Green's functions, Fredholm Alternative.

Partial Differential Equations:

well-posed problems, maximum principles, energy argument (Lyapunov functions), orthogonal expansions, Fourier Transforms, heat kernel.
