Subject: Lightning Laplace and conformal mapping codes

I am happy to announce the availability of Matlab codes LAPLACE and
CONFMAP to solve Laplace Dirichlet problems and compute conformal maps
in polygons, circular polygons, and other simply-connected planar
domains. These codes make use of the "lightning Laplace" algorithm,
involving rational functions with poles exponentially clustered near
corner singularities. Typical problems are solved to 6-10 digits of
accuracy all the way up to the corners in less than a second on a
laptop, with subsequent function evaluations requiring microseconds
per point.

Details can be found at

https://people.maths.ox.ac.uk/trefethen/lightning.html, which shows

example plots produced by executing laplace('L') and confmap('iso').

CONFMAP requires Chebfun in the Matlab path (because it uses AAA
rational approximations), but LAPLACE does not.

Subject: CFP, Organize the Next Householder Symposium

Against the backdrop of COVID-19's spread, the Householder Committee
has decided to cancel the Householder Symposium 2020 in Selva di
Fasano. It is intended to organize the next Householder meeting in
June 2022 (instead of 2023) in Selva di Fasano followed by meetings in
2025, 2028, ....

For this reason, the call for proposals to organize the 2023
Householder Symposium has been changed to a call for proposals to
organize the 2025 Houeholder Symposium. The deadline for submitting a
proposal will be April 1, 2022. Further information will be available
in due course. We apologize for any inconvience this may cause.

Subject: PhD Position, Cardiff Univ

EPSRC DTP studentship in Least Squares PGD Mimetic Spectral
Element Methods for Systems of First-Order PDEs

Many mathematical models that describe problems in science and
engineering are defined in high dimensional spaces. The mathematical
description of these problems is invariably in terms of a system of
partial differential equations (PDEs). For practical problems these
systems do not possess analytical solutions and therefore it is
necessary to solve them numerically. It is important that the system
of algebraic equations obtained as a result of discretisation is a
compatible (mimetic) and physically consistent system so that the
numerical approximation is an accurate representation of the physical
solution to the problem. The governing systems of PDEs is written in
terms of an equivalent system of first-order differential equations
which is subsequently formulated in terms of a least squares
functional. The exceptional stability of least-squares formulations
has led to the widespread use of low-order finite elements in their
discretization. Unfortunately, these methods are only approximately
conservative, which generally leads to violation of fundamental
physical properties, such as loss of mass conservation. In many cases
this drawback can outweigh the potential advantages of least squares
methods. As a result, improving the conservation properties of
least-squares methods is crucially important.
