Skills and learning outcomes
Description of contents: programme
1. Advanced Topics in Measure theory. 2. Best approximation in normed spaces. Existence and uniqueness. 3. Uniform approximation of continuous functions with algebraic polynomials. 4. Approximation with algebraic and trigonometric polynomials in L2. 5. Approximation with algebraic polynomials in L1. 6. Interpolation and approximation with splines. B-splines. Computation and applications. 7. Frame analysis. 8. Approximation with rational functions. Padé Approximants. Applications.
Learning activities and methodology
The docent methodology will include: * Master classes, where the knowledge that the students must acquire will be presented. To make easier the development of the class, the students will have written notes and also will have the basic texts of reference that will facilitate their subsequent work. * Resolution of exercises by the students, in which proposed problems are discussed and developed (by the professor and by the students). These classes allow to the students to acquire the necessary skills. * Additionally, there will be tutorial learning activities. These tutorial activities will be supervised and they will have theoretical and practical content. The rest of the working hours will be dedicated to the student's study. During this time the student can have access to the computer room.
