Radii Petrovich Fedorenko, March 11, 1930 - September 13, 2009

Radii Petrovich Fedorenko, a multigrid pioneer, passed away on September
13, 2009 after a long illness.

Radii P. Fedorenko graduated from Mathematics program of Mathematics and
Physics Faculty, Rostov State University in 1953. He spent all his long
scientific career at Keldysh Institute of Applied Mathematics, having
started at the Department headed by Israel M. Gelfand. The institute
was the mathematical brain behind many major scientific accomplishments
of the post-war USSR, including the Russian nuclear and space programs.
Although in the west Fedorenko is mostly known as a multigrid pioneer,
his research interests were amazingly broad and the scope of his
contributions is impressive. Except the multigrid (with the first
three papers published in 1961, 1964 and 1973), these included schemes
with switching order to overcome the Godunov barrier (a 1962 paper),
optimal control (PhD thesis in 1965, a long list of papers and a book
in 1978), variational analysis (e.g. results on the price existence
in differential pursuit game and a maximum principle for differential
inclusions and non-smooth variational inequalities), the first enthalpy
finite-difference scheme for Stefan problems (paper in 1975), mathematical
modeling of nuclear reactors which motivated creation of his finite
super-element method (a residual free bubble's ancestor, since 1976), as
well as his work on stiff time integrators (since 1983). Since 1994 he
also worked on numerical solution of Lame equations.

Many years of teaching courses on Numerical Methods in the Phystech
(Moscow Institute of Physics and Technology, the Russian MIT) inspired
Fedorenko to write a book "Introduction to Computational Physics" with
first edition printed in 1994 - one of the most unorthodox and informal,
yet wonderful books on the subject.

Fedorenko had hardly ever trusted doing numerical experiments to his
cohorts, all the experiments in his papers were carried out by him. His
last big code was a Fortran 95 higher-order finite element implementation.
Radii Fedorenko was a modest and kind person, highly respected by many
who knew him. He will be strongly missed by his family, colleagues,
and students. He is survived by his wife and children.

In 2001 Fedorenko wrote a short note on multigrid history, an English
translation of it can be found at

Subject: Re: Potentially serious bug in Matlab R2009b

Following up to the message in the Nov 30, 2009 NA Digest:

Thanks to all the MATLAB Community members who have reported this bug
and forwarded this information along.

We have posted this Bug (583443) in our Bug Report system:

Look under MATLAB, in the Mathematics Category, Exists In R2009b.

MATLAB customers should feel free to Watch this Bug for any updates,
or Subscribe to an RSS feed of a group of Bugs of interest.

This Bug Report details the circumstances required to trigger the bug.

The summary is that A must be the permutation of a full, square, non-scalar
triangular matrix (but not exactly triangular) and must be used as A’\b in
the solve.

The Bug Report does not yet reflect this, but the bug will be fixed in our
next release of MATLAB.

Subject: MPSpack: a MATLAB toolbox for Helmholtz BVPs in 2D

We announce the release of version 1.0 of MPSpack, an object-oriented and
user-friendly MATLAB toolbox for the efficient and often spectrally
accurate numerical solution of Helmholtz, wave scattering, Laplace, and
related PDE boundary-value problems on piecewise-homogeneous 2D domains,
including those with corners.

Our philosophy is to represent solutions on one or a few large subdomains
with basis functions which are particular solutions to the PDE, and use
least-squares matching on interfaces and boundaries. This is known variously
as the method of particular solutions, Trefftz methods, or non-polynomial
finite elements. Basis function types include plane-wave, Fourier-Bessel
(cylindrical), corner-adapted wedge expansions, fundamental solutions, and layer
potentials (with associated singular quadrature schemes). These can be combined
in a flexible fashion. We designed the user interface to objects (segments,
domains, bases, etc) to be as clean and simple as possible.

Interior and exterior BVPs, sound-soft/sound-hard acoustic scattering and
transmission problems may be set up and solved, with accuracy often close to
machine precision, in 10-20 lines of quite intuitive code.

MPSpack is freely available for download at

There is also a manual, and tutorial that takes the user through many worked
examples, including lots of pretty pictures of what MPSpack can do.

Subject: Multi-scale for multi-phase porous media flow, Edinburgh, Jan 2010

"Novel multi-scale methods for multi-phase porous media flow"

to be held at the International Centre for Mathematical Sciences
(ICMS) in Edinburgh on 18-19 January 2010.

Confirmed speakers:
Martin Blunt
Yalchin Efendiev

Rainer Helmig
Patrick Jenny
Ruben Juanes
Rink van Dijke
Mary Wheeler

The meeting will examine novel mathematical approaches for modelling
multi-phase flow (e.g., oil, gas, water) in porous media.
Three-phase flow occurs in petroleum engineering, for example when gas is
injected into a reservoir that is past its peak production to recover
additional volumes of oil. The gas phase may be carbon dioxide, which has the
additional benefit of storing this greenhouse gas underground. Novel
descriptions are sought for flow processes on the length scale of meters to
kilometres, while incorporating the physical processes occurring on the
millimeter scale or smaller (e.g., mobilisation of blobs of oil that have
become trapped in the porous reservoir rock). Robust and efficient numerical
algorithms, supported by sound mathematical theories and proofs, are of wide
importance in all engineering disciplines and in particular in this field for
accurate flow predictions.

Subject: PhD position at K.U.Leuven, Belgium

PhD position on
"Algorithmic advances based on low-discrepancy point sets"
(K.U.Leuven, Belgium).

The aim of this research project is to investigate shortcomings of
existing computational techniques situated in numerical integration
and to develop new algorithms, mainly based on low-discrepancy point
sets, tailored for specific problems. Such techniques are called
quasi-Monte Carlo methods, and, in contrast to the standard Monte
Carlo method, use low-discrepancy point sets instead of random point

The main objectives of this project are the development of new
algorithms related to low-discrepancy point sets and the development
of end-user software for the application of low-discrepancy points.

The research will be carried out at the Numerical Analysis and Applied
Mathematics Section at the Department of Computer Science of the
K.U.Leuven in the team of prof. Ronald Cools and Dr. Dirk Nuyens.
The K.U.Leuven is one of the oldest universities of Europe (est. 1425),
located in the cosy town of Leuven, 20 km from Brussels, in the hearth
of Europe.

Subject: Cambridge Centre for Analysis

I wish to let the NA-net community know about the new Cambridge Centre
for Analysis.

The CCA is a Centre for Doctoral Training in Mathematical Analysis, a
joint project of the two mathematics departments in Cambridge under
the directorship of Arieh Iserles and James Norris, funded by the UK
Engineering and Physical Sciences Research Council and by University
of Cambridge. We intend to admit each year about fifteen research
students in all areas of mathematical analysis: pure, stochastic,
computational and applied, and train them for four years toward a
Cambridge PhD. More details are available at .

Most of our students will be funded by EPSRC. This means that EU
nationals resident in UK for at least three years will receive both
tuition costs and maintenance, other EU nationals being eligible only
for tuition costs. Yet, on past record, we believe that we'll be able
to cover maintenance of most our EU students from other sources. In
addition, we'll have four Cambridge-funded scholarships, open to all
candidates without restriction of nationality.

I would like to bring this to the notice of suitable candidates. We
are currently seeking first-class young mathematicians, typically in
either the final year of four-year (or longer) mathematics degree
course or currently undergoing MSc training, who wish to conduct their
PhD research in one of the areas of mathematical analysis, emphasising
both research excellence and the breadth of knowledge and intellectual
curiosity essential, we believe, to successful work in mathematical
