Prerequisites: Numerical Analysis
Target skills and knowledge: Advanced knowledge of Numerical Analysis and its applications in Applied Mathematics.
Examination methods: Written exam (theory) and oral exam (laboratory).
Assessment criteria: In the written examination we understand the theoretical knowledge obtained by the student, with particular attention to the comprehension of the algorithms, their properties, and proofs of major theorems.

In the part of lab, we evaluate how much the students have programming skills as well as understanding of the performed numerical experiments.
Course unit contents: Interpolation.
Orthogonal polynomials.
Numerical quadrature.
Iterative methods for linear algebra.
Nonlinear systems.
Finite differences methods for ODEs and PDEs.
Planned learning activities and teaching methods: Interpolation.
The general problem of interpolation, unisolvent sets and determinantal formula of Lagrange, the univariate and multivariate case, Lebesgue constant, fundamental estimate for interpolation error, stability, brief introduction to tensorial product interpolation and Fekete points.

Orthogonal polynomials.
Orthogonalization of the monomial basis, three-terms recurrence, the theorem of the zeros, classical orthogonal polynomials, Chebyshev polynomials.

Numerical quadrature.
Algebraic and composite rules, Gaussian rules, Polya-Steklov theorem, stability, Stieltjes theorem, brief introduction to product rules.

Numerical linear algebra.
Fundamental theorem of matrix inversion and applications (Gershgorin theorem of eigenvalues localization), iterative methods for linear systems, successive approximation theorem, preconditioning, gradient method, step and residual stop criteria, methods for the computation of eigenvalues and eigenvectors, Rayleigh quotient, power method and variants, QR method.

Numerical nonlinear algebra.
Solution of nonlinear systems of equations, fixed point iterations and Banach theorem, convergence estimates and stability, Newton method, local convergence and speed of convergence, step criterion, Newton method as fixed point iteration.

Finite difference methods for ODEs and PDEs.
Initial value problem: Euler method (explicit and implicit), convergence and stability in the Lipschitzian and dissipative case, trapezoidal method (Crank-Nicolson), stiff problems, conditional and unconditional stability; boundary problems: finite difference methods for the Poisson equations in 1D and 2D, structure of the linear system and convergence, computational issues; the lines method for the heat equation in the 1D and 2D case, relationships with the stiff problems.
