Can anyone point us to software that can solve the Laplace equation on polygons with 8-digit accuracy all the way to the corners? Various methods can handle such problems in principle, but we are looking for actual software for comparisons with our own new method under development. Here's an example problem. Let the domain be the L-shaped region in the (x,y)-plane consisting of [0,2]x[0,2] minus its upper-right quarter. If u is harmonic in this region with u = x^2 on the boundaries, what is u(.99,.99) to 8 digits? Many thanks, - Nick Trefethen and Abi Gopal ------------------------------------------------------- From: Jan S Hesthaven [log in to unmask] Date: November 29, 2018 Subject: ICERM Scientific Machine Learning, USA, Jan 2019 The machine learning revolution is already having a significant impact across the social sciences and business, but it is also beginning to change computational science and engineering in fundamental and very varied ways. We are experiencing the rise of new and simpler data-driven methods based on techniques from machine learning such as deep learning. This revolution allows for the development of radical new techniques to address problems known to be very challenging with traditional methods and suggests the potential dramatic enhancement of existing methods through data informed parameter selection, both in static and dynamic modes of operation. Techniques are emerging that allows us to produce realistic solutions from non-sterilized computational problems in diverse physical sciences. However, the urgent and unmet need to formally analyze, design, develop and deploy these emerging methods and develop algorithms must be addressed. Many central problems, e.g., enforcement of physical constraints in machine learning techniques and efficient techniques to deal with multiscale problems, are unmet in existing methods. The primary goal of this Hot Topic workshop is to bring together leading researchers across various fields to discuss recent results and techniques at the interface between traditional methods and emerging data-driven techniques to enable innovation in scientific computing in computational science and engineering.

Students come from all over Europe to spend a week working in small multinational groups on projects which are based on real-life problems. The main aims of the Modelling Weeks are to train students in Mathematical Modelling and stimulate their collaboration and communication skills, in a multinational environment. Attendance at a Modelling week is an integral part of the ECMI certificate and of many of the masters courses run at ECMI centres but many other students have also learned new skills by attending one of these very successful courses.

Remuneration is based on salary group E 13 TV-L (100%) and the position is filled for an initial period of three years. An extension is possible. The tasks include the support of the professorship "Nonlinear Optimization" in research and teaching as well as the participation in the organization of the professorship. The opportunity for a doctorate is given. Nonlinear optimization is a very active field of research, especially in the context of mixed-integer problems. In the working group, theoretical properties of this problem class are analyzed and algorithms for the solution of mixed-integer nonlinear optimization problems are developed. A further topic is equilibrium problems, which are analyzed theoretically (exemplary questions are the existence and uniqueness of solutions) and for which solution methods are also developed. Many of the current questions in the working group are motivated by technical- physical or economic aspects in the field of energy, such as the cost- effective control of gas transport networks or the analysis of electricity trading in Germany. The applicant is expected to enjoy working in a team and to enjoy applied mathematical research. We also expect the candidate to be able to work independently, to be reliable, willing to work in an interdisciplinary environment, and to have a good and English languages skills. The prerequisite for employment is a university degree in mathematics (within the meaning of S56 Para. 2 No. 1 HochSchG). A focus on optimization subjects during the studies is desirable. Severely handicapped persons are given preferential employment if they are suitable. The University of Trier is endeavouring to increase the number of its female academics and urges them to apply.

In Europe alone, the annual cost due to flood damage is expected to rise to 100 billion EUR by the year 2080, due to a combination of climate change and socio-economic growth. Timely flood inundation forecasts allow pro-active flood management, mitigating against loss of life and damage to key infrastructure. The goal of this PhD project is to investigate new mathematical methods using observations of floods to verify and improve flood inundation forecasts.
