Beschreibung |
In recent years, the mathematical formulation and the development of efficient simulation methods for Partial Differential Equations (PDEs) with random inputs and with noisy data has become increasingly important in engineering and the sciences. We think of parabolic SPDEs driven by Wiener and Levy noise in term structure models in finance, wave propagation in random media in the geosciences, porous media flow in media with uncertain permeability in subsurface flow models; in the life sciences, PDEs arise on high or even infinite dimensional parameter spaces, such as the master equation or mass action models with hundreds of species in bioengineering. In the seminar, we will discuss the mathematical formulation, regularity, adaptive approximation and numerical analysis of Partial Differential Equations (PDEs) with random input data and on high dimensional parameter spaces. Mathematical Topics to be discussed include: Multi-Level Monte Carlo Methods, Multi-Level Quasi Monte Carlo Methods, Polynomial Chaos type representation of random fields, Adaptive solvers for PDEs, Smolyak tensor interpolation algorithms, Bayesian inverse problems for PDEs, Massively Parallel Uncertainty Quantification algorithms. All topics benefit current research projects in SAM, in particular to the European Research Council project `` Sparse Tensor Approximation of High Dimensional PDE '' and can lead to MSc resp. PhD thesis work in MATH and in in RW/CSE. Format of the seminar: MATH students will read selected recent research papers on the seminar's mathematical topics, prepare +an oral presentation and +a written summary of their presentation. Student presentations will take place either during November or during the last week of HS2011. RW/CSE students can replace the written mathematical summary by an implementation.
The number of participants is limited to 10. |
