SF1682 Analytical and Numerical Methods for Differential Equations
KTH Royal Institute of Technology
Completed basic course SF1626 Calculus in Several Variable.
- Equations: First and higher order ordinary differential equations and systems of these, partial differential equations (e.g. for heat and waves).
- Transforms: Fourier transform, Laplace transform and Fourier series.
- Analytical concepts: Initial value problems, boundary value problems, existence and uniqueness of solutions, autonomous equations, direction fields, phase portraits, solutions curves, oscillation phenomena, general solution, particular solution, stationary/critical points, stability, linearization of systems, the delta function, generalized derivatives.
- Numerical concepts: Apprximation, discretization, convergence, conditional number, accuracy, local linearization, stability, stiff systems, implicit and explicit methods, adaptivity.
- Analytic methods: Integrationg factor, separation of variables, variation of parameters, eigenvalue methods, transforms, spectral methods.
- Numerical methods: Newton's method for non-linear systems, Euler forward, Euler backwards, Runge_kutta methods, finite difference methods, spectral methods, fast Fourier transform (FFT), computational complexity.
After the course the student should be able to
- use concepts. theorems and methods to handle questions in analysis and numerical aspects of differential equations and transforms described by the course content,
- use analytical and numerical methods to solve the the differential equations described by the course content, and gain insights into the possibilities and limitiations of methods.
- read and comprehend mathematical text.
