| Subject |
- Numerical errors, floating-point numbers
- Basic numerical analysis: Interpolation, differentiation, finding roots, quadrature (newton-cotes, Gauss quadrature)
- Solution of initial value problems for systems of ODEs: Euler-, Runge-Kutta-, Predictor-corrector methods, symplectic integrators
- Three-body problem, introduction to classical chaos
- Boundary- and Eigenvalue problems
- Finite difference discretization
- Finite element discretization
- Iterative solution of linear systems (Jacobi, Gauss-Seidel, SOR, Conjugate Gradient methods, preconditioning)
- Iterative solution of eigenvalue problems (Inverse iterations, Rayleigh quotient iterations, subspace iteration method, Lanczos method, generalized eigenvalue problems)
- Introduction partial differential equations
|
| Criteria for evaluation |
2 term papers:
- celestial mechanics problem (chaotic motion in the 3-body problem, Lagrange points)
- finite element simulation (Schrödinger equation of a quantum dot)
The grade for the lecture is based on quality and "scientific soundness" of the papers turned in.
