401-3650-15L

Semester Spring Semester 2015
Lecturers Dr. Peng Chen and Prof. Christoph Schwab
Time Thursday 15:15-17:00
Place HG F 26.3
Abstract The seminar is concerned with the recently developed computational reduction methods, including Reduced Basis Method (RBM), Proper Orthogonal Decomposition (POD), Empirical Interpolation Method (EIM), and their application in solving high-fidelity and high-dimensional parametric and stochastic Partial Differential Equations (PDEs).
Objective During the semester each participant is supposed to prepare a two-hours lecture, which is to be given in May 2015. It should be based on at least two of the recent research papers listed below. Depending on the student's preferences and study program, the focus may be made on the fundamentals, implementation aspects or application of these methods. The students are encouraged to conduct some original research. Help and guidance will be provided during the whole semester by the lecturers.
Prerequisites / Notice The number of participants of the seminar is limited to 6. The preference will be given to ETH students of the following programs:

1. ETH MSc Applied Math,
2. ETH MSc RW/CSE,
3. ETH MSc MATH.
4. ETH BSc MATH,

The prerequisites are:

(*) for students taking the seminar for ETH BSc MATH: completed BSc examinations in Numerische Mathematik I+II, Numerical Methods for Elliptic and Parabolic PDEs.

(*) for students taking the seminar for ETH MSc Math, Applied Math, RW/CSE: completed exam in courses Numerical Methods for Elliptic and Parabolic PDEs, OR NumPDEs for RW/CSE, Numerical Analysis of Stochastic PDEs.

Topics will be discussed and selected for each participant during the first meeting on Thursday, Feb 19th, from 15h15 to 17h00, in the room HG F 26.3.
