Hi PhysicsForum!(adsbygoogle = window.adsbygoogle || []).push({});

Fall 2012 semester will be my last semester as an undergrad in Math and Statistics and I was planning on taking a handful of graduate level classes. I'm planning on applying to grad school in Applied Math and concentrating on differential equations, fluid dynamics, or stochastic processes. I wanted an opinion on the classes I would be choosing.

I am for sure going to take

Numerical Fluid Dynamics:

Addresses numerical techniques for solving linear and nonlinear differential equations in initial value fluid flow problems. Students receive a thorough background in the principles used to evaluate numerical methods, the ability to critically interpret these methods as presented in the literature, and in particular, the practical application of these techniques in modeling multi-dimensional flow on high-performance computers. Temporal and directional splitting, finite differencing/volume methods, and adaptive nesting will be discussed.

and

Measure Theory:

Lebesgue measure on the real line; integration and differentiation of real valued functions of a real variable; and additional topics at discretion of instructor.

But I'm not sure what else to take. I want to taketwomore classes, but I don't know if I should lean towardstheory(i.e. Differential Equations or Complex Analysis) orcomputing(Numerical Methods), especially since I want to do applied math in grad school. Here are the course descriptions for the classes I'm trying to decide between.

Graduate ODEs:

An introduction to the study of dynamical systems. Considers continuous and discrete dynamical systems at a sophisticated level: differential equations, flows and maps on Euclidean space and other manifolds. Emphasis will be placed on the fundamental theoretical concepts and the interaction between the geometry and topology of manifolds and global flows. Discrete dynamics includes Bernoulli shifts, elementary Anosov diffeomorphisms and surfaces of sections of flows. Bifurcation phenomena in both continuous and discrete dynamics will be studied.

Graduate PDEs:

Basic introduction to the study of partial differential equations; topics include: the Cauchy problem, power-series methods, characteristics, classification, canonical forms, well-posed problems, Riemann's method for hyperbolic equations, the Goursat problem, the wave equation, Sturm-Liouville problems and separation of variables, Fourier series, the heat equation, integral transforms, Laplace's equation, harmonic functions, potential theory, the Dirichlet and Neumann problems, and Green's functions.

Graduate Complex Analysis:

Topics include the Cauchy theory, harmonic functions, entire and meromorphic functions, and the Riemann mapping theorem.

or

Numerical Analysis:

Linear system solvers, optimization techniques, interpolation and approximation of functions, solving systems of nonlinear equations, eigenvalue problems, least squares, and quadrature; numerical handling of ordinary and partial differential equations.

TL;DR: What is more important in preparation for applied math PhD programs, math theory or computing knowledge. Will I get enough computing knowledge from the Numerical Fluid Dynamics class? Which two other classes should I choose.
