Subject: 8-digit Laplace solutions on polygons?
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
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

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
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.

Subject: PhD Position, Nonlinear Optimization, Trier Univ
In the Faculty IV (Department of Mathematics) at the Trier University,
a PhD position in "Nonlinear Optimization" is to be filled as soon as
possible. 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
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. Applications with the usual documents (letter of
motivation, curriculum vitae, certificates and, if applicable, list of
publications as well as a list of courses supervised to date) in a PDF

Subject: PhD Position, Univ of Reading, UK
PhD project available at the University of Reading, UK Enhancing
forecasting flood inundation mapping through data assimilation
Flooding is major risk for lives and livelihoods around the world. 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.
