Time 10.15
Speaker Prof. Dr. Thomas Wihler, Mathematical Institute, University of Bern
Location Universität Bern, Institut für Angewandte Physik, Gebäude exakte Wissenschaften, Hörsaal B116, Sidlerstrasse 5, 3012 Bern
Program In this talk we will present an elementary yet very effective numerical method for the approximation of (possibly unknown) data. To this end, piecewise polynomial functions of possibly varying local degree will be employed. Here, the goal is to design a computationally inexpensive procedure that is able to produce high quality approximations by determining the length of the local intervals and the approximation orders automatically. Particular interest will be put on data that is not known explicitly as is the case, for example, in the numerical solution of differential equations. The talk is suitable for a broader audience of scientists.
