| 252-0504-00L | Numerical Methods for Solving Large Scale Eigenvalue Problems  The course will be offered for the last time. | 4 credits | 3G | P. Arbenz | |
| Abstract | In this lecture algorithms are investigated for solving eigenvalue problems with large sparse matrices. Some of these eigensolvers have been developed only in the last few years. They will be analyzed in theory and practice (by means of MATLAB exercises). | ||||
| Learning objective | Knowing the modern algorithms for solving large scale eigenvalue problems, their numerical behavior, their strengths and weaknesses. | ||||
| Content | The lecture starts with providing examples for applications in which eigenvalue problems play an important role. After an introduction into the linear algebra of eigenvalue problems, an overview of methods (such as the classical QR algorithm) for solving small to medium-sized eigenvalue problems is given. Afterwards, the most important algorithms for solving large scale, typically sparse matrix eigenvalue problems are introduced and analyzed. The lecture will cover a choice of the following topics: * vector and subspace iteration * trace minimization algorithm * Arnoldi and Lanczos algorithms (including restarting variants) * Davidson and Jacobi-Davidson Algorithm * preconditioned inverse iteration and LOBPCG * methods for nonlinear eigenvalue problems In the exercises, these algorithm will be implemented (in simplified forms) and analysed in MATLAB. | ||||

| 252-5251-00L | Computational Science Takes place for the last time. | 2 credits | 2S | P. Arbenz, P. Chatzidoukas | |
| Abstract | Class participants study and make a 40 minute presentation (in English) on fundamental papers of Computational Science. A preliminary discussion of the talk (structure, content, methodology) with the responsible professor is required. The talk has to be given in a way that the other seminar participants can understand it and learn from it. Participation throughout the semester is mandatory. | ||||
