Subject: PLTMG version 11

PLTMG 11.0 is a package for solving elliptic partial differential
equations in general regions of the plane. It is based on a family of
continuous Lagrange triangular finite elements. PLTMG features
options for adaptive h, p, and hp refinement, coarsening, and mesh
moving. PLTMG employes several algebraic multilevel solvers for the
resulting systems of linear equations. PLTMG provides a suite of
continuation options to handle PDEs with parameter dependencies. It
also provides options for solving several classes of optimal control
and obstacle problems. The package includes an initial mesh generator
and several graphics packages. Support for the Bank-Holst parallel
adaptive meshing paradigm and corresponding domain decomposition
solver are also provided.

PLTMG is provided as Fortran (and a little C) source code. The code
has interfaces to X-Windows, MPI, and Michael Holst's OpenGL display
tool SG. The X-Windows, MPI, and SG interfaces require libraries that
are NOT provided as part of the PLTMG package. PLTMG is available
from Netlib and the author's homepage:

Subject: PhD Position, NA, Univ of Zurich, Switzerland

PhD Position in Numerical Analysis

The PhD student will be part of the Zurich Graduate School in
Mathematics, working in the group of Numerical Analysis (Dr. Maria
Lopez-Fernandez and Prof. Stefan Sauter) at the Institute of
Mathematics, University of Zurich, Switzerland.

Topic: Time-Space adaptive solution of time domain boundary integral

The efficient approximation of time domain boundary integral equations
has become a very active field of research in the last years. The
applications in engineering are many since the scattering of both
acoustic and electromagnetic waves in unbounded exterior domains can
be modeled in this way. From the computational point of view the main
bottleneck of these models comes from space-dependent delays in time
which appear in the resulting retarded integral equations. The main
concerns in this setting are the computational cost and the memory

This area has been an active topic of research during the last years
and the current state of the art allows for high order fast and stable
algorithms to approximate these problems. However, most of these
methods only work with uniform step size. So far the inclusion of
adaptivity in time and space to approximate time domain boundary
integral equations is in general an open and important issue.

The major goal of this research project is the development of fast and
stable algorithms which are able to adapt both the time steps and the
space mesh in a dynamical problem-adapted way. Our model problem will
be the boundary integral formulation of the wave equation.

A fine combination of numerical methods will be needed in order to
carry out this project, which involves several central areas in
Numerical Analysis: numerical methods for ODEs and PDEs, complex
analysis techniques and good programming skills.

Starting Date: September 2012 or later.

Requirements: Master degree in applied mathematics with outstanding
grades; fundamental knowledge in the area of numerical methods for
ODEs and, optional but desirable, for PDEs; programming skills in
MATLAB; programming skills in Java or C would be considered a valuable
additional asset.

Funding: The project is sponsored by the Swiss National Science
Foundation. The salary is above 40.000 CHF per year.

To apply, please send by email a full CV, a cover letter and three
reference letters to Dr. Maria Lopez-Fernandez:, until August 31, 2012.
