Subject: Who Invented Euler's Method?
History question:
Why is Euler's method (for discretizing ode's) called Euler's
method? Did Euler invent it? If not he, then who? And who
is responsible for distinguishing between the explicit and
implicit versions as "forward" and "backward"?

Subject: Solution Method in Search of Problems
Consider the following mathematical problem: Given e>0 and complex constants
Cjk, j=2,3,...,N, k=1,2,...,j, find dj such that
|C21 + C22*exp(i*d2)| < e
|C31 + C32*exp(i*d2) + C33*exp(i*d3)| < e
.
.
.
|CN1 + CN2*exp(i*d2) + ... + CNN*exp(i*dN)| < e
This mathematical problem arises from the physical problem of trying to limit
the radial runout of combustion turbine rotors constructed of disks stacked
face-to-face. These disks have machining errors resulting in the faces being
non-parallel and not aligned. The variables dj are the angular orientations
of the disks.
I have developed a method of finding a solution to this problem by converting
the (N-1)-dimensional search problem into (N-1) sequential one-dimensional
search problems. For N=100 I find a solution in a few seconds on a PC.
Does anyone know of any other physical problems which are described
mathematically by the above set of inequalities?

One can of course learn all one wants to know about the classic

curious if anyone has archived collections of "non-standard" orthogonal

there is something out there I can use.

Subject: Coupled Eigenvalue Problem
Hi:
I have a coupled eigenvalue problem like
KX+P^T Y=\omega^2 MX,
PX-QY=0.
The coupling matrices P and Q have very small elements comparing with
the principal one, K. For the first part, KX-\omega^2MX=0, I can
solve it without any problem. To consider the coupling, I am trying
to form a general matrix problem like
GZ-\omega^2 LZ=0,
with
G=[K P^T] L=[M 0] Z=[X]
[P - Q], [0 0], [Y].
Apparent this does not work. In the past, people are using
pertubation method to get solutions.
Are there any techniques to solve the generalized problem rather
than going to using perturbation?
Any comments and suggestions are welcome.

Subject: Note from a Colleague in Azerbaijan
Dear colleagues,
I want to remind you of the economical situation in our Republic of
Azerbaijan, because of it we cannot receive scientific journals
and we are distracted from scientific world. Naturally scientific
world cannot receive some information about our researches.
Therefore I want to know, how can you help me? Maybe for finding
some funding to support my participate in conferences (I received
some invitation from the conferences. Problem is in financial difficulty)
or help me to fined some position for teaching at the Universities.
I send you some information about me.
We inverstigate nimerical solution of the initial value problem
for the ODE arbitrary orders. For this aim consider multistep
multiderivative methods (k-step Obrechkoff's methods) with
constant coefficients. We determined the maximal values of the
degree (maximal exactness of the considered methods) for the stable
explicit, implicit and forward-jumping methods. Also we inverstigated
l-stable methods. We suggested multistep multiderivative methods for
solving ODE arbitrary orders and show that it is effective.
Constructed A-stable method with the high degree ( degree p>2) by
the k-step method with the arbitrary coefficicnts and by the multistep
multiderivative forward-jumping methods. These results are developming
some G.Dahlquist and A.Iserles and S.P.Norsett's results. Now we
research to determine the sign of some coefficients in multi-step
multiderivative and in k-step forward-jumping method and relation
among them.
More information about my work, including a curriculum vitae, is
available on request.

NEW CODE
This is to announce a new code mebdfdae.f for the solution of
stiff initial value problems and differential algebraic equations
in linearly implicit form. The underlying algorithm is
based on modified extended backward differentiation formulae.
These formulae have considerably better stability than BDF and
are A-Stable up to order 4 and A(alpha)-Stable up to order 9.
Results for mebdfdae.f on the stiff DETEST test set together with
the corresponding results for STRIDE, RADAU5, LSODE and DESI
(which may be used as comparisons) are available by anonymous ftp
and the web. Also available are results for most of the test
problems in the book of Hairer and Wanner. The main addition is that
results are also given for a set of DAEs of index 1-3 taken
from a variety of texts. These include pendulum problems, spring
problems and some of the challenging problems from the Amsterdam test
set.
The code, drivers and results are available from:

constitute the spinal chord of modern mathematical
modelling of combustion phenomena.

Combustion Theory and Modelling
(gaetano@irc.na.cnr.it)
Announcement of a new journal: Combustion Theory and Modelling
Combustion Theory and Modelling is a new quarterly journal
by the Institute of Phisics Publishing, for the publication
and dissemination of scientific articles that apply mathematical
theory, modelling, numerical simulation and experimental
techniques to the study of combustion.
Editors-In-Chief are Bill Dold, UMIST, Manchester, UK
and Mitch Smooke, Yale University, New Haven, CT, USA.
With its international Editorial Board, Combustion
Theory and Modelling will focus on providing the highest
quality forum for articles that explain combustion phenomena
and that explore the predictions and properties of
combustion models from a modern mathematically-based viewpoint.
The journal encourages submissions on fundamental theoretical
investigations into all aspects of combustion, aimed at gaining a
deeper understanding of its various phenomena and at strengthening
the predictive power of theoretical methods.
Articles can cover a wide range of topics such as: premixed
laminar flames, laminar diffusion flames, turbulent combustion,
fires, chemical kinetics, pollutant formation, microgravity,
materials synthesis, vapour deposition, catalysis, droplet and
spray combustion, detonation dynamics, thermal explosions,
ignition, energetic materials and propellants, burners and engine
combustion. A wide range of mathematical methods may also be
used, including large scale numerical simulation, hybrid
computational schemes, front tracking, adaptive mesh refinement,
optimised parallel computation, asymptotic methods and singular
perturbation theory, bifurcation theory, optimisation methods,
dynamical systems theory, cellular automata and discrete
methods, probabilistic and statistical methods, and rigorous
proofs for mathematical problems that are posed directly from
models of combustion.
Combustion Theory and Modelling also accepts multimedia
material and would like to encourage the submission of
multimedia supplements to regular articles.
Submissions should be sent to

Company, Lord Corporation and National Security Agency. The problem
presenters for this year Workshop are being recruited and their names
will be announced subsequently.
