Description: |
Direct numerical approximation of high frequency wave propagation typically requires a very large number of unknowns and is computationally very costly. We will discuss two aspects of this type of problem. One is the development and analysis of fast algorithms of optimal computational complexity for boundary integral formulations and variable coefficient differential equations. The other aspect is analysis revealing when algorithms of the type mentioned is possible and when it is not. A key feature is compression of a discrete operator related to the solution.
