Within the Hot Topic session on Mathematics in developing countries at the Heidelberg Laureate forum, Peter Benner and Hermann Mena (University of Innsbruck) will jointly speak about their former German-Ecuadorian cooperation on simulating the spray-drift at the Ecuador-Colombian border caused by spraying herbicides to destroy coca plants. See Max Planck Research 1/2015 for details of the project.
The 3rd Symposium of the German SIAM Student Chapters
toke place in Magdeburg on 28.-29. of August 2014. We welcomed
guest from the other German SIAM Chapters in Heidelberg
and Trier. For the first time, members of the SIAM
Chapter in Prag participated to extend the international connections.
The article "Model Order Reduction for Systems with Moving Loads" by Peter Benner, Norman Lang and Jens Saak has been published at June 28 2014, in De Gruyter Oldenbourg: at-Automatisierungstechnik: volume 62 (7).
Norman Lang, Hermann Mena, and Jens Saak present an LDLT based version of the standard low-rank Lyapunov solvers based on ADI or Krylov subspace methods. The method allows us to avoid complex arithmetic for the solution of matrix differential equations via higher order time integration methods, as well as the a priori reduction of the number of columns in the right hand side of the arising algebraic Lyapunov equations inside of the time integration loop.
