Subject: Variation on the Harmonic Series Question

For an amusing variation on the quiz question presented
by John C. Nash, pick any integer between 0 and 9. Call
this integer M.

Remove every term from the harmonic series that contains
M as one of the digits in the denominator. For example,
if M = 3, then remove 1/3, 1/13, 1/23, 1/30, 1/31, ...

What is the behavior of the remaining series

o in the real numbers?

o on a computer?

Subject: Mathematical Model for Volterra-Fredholm Equations

I am studying on a numerical simulation of heat transfer by
simultaneous radiation and conduction in a semitransparent
media and I have to solve some integrodifferential equations.
Specially, the nonlinear Volterra or Fredholm equations of
second kind.

If you have some information or code (Fortran77 or C) for my problem,
Thanks.

Subject: A Second Order ODE

I am interested in solving the following 2nd order ODE for y(x):

x*y''+y'+x*(1-b*x^2)*y=0

where x is positive, and b is a positive constant.

My first question: Is y(x) "special" in the sense that it can be
related simply to a function named after a dead mathematician?

My second request: I am interested in obtaining an algorithm for
generating a solution to this ODE which also satisfies the BC that
the limit (as x->0) of y(x)/ln(x) equals unity. The only way that
I know is to generate two power series, first for the particular
solution [y_1(x)] which is well-behaved at the origin and next for
the solution given by y_2(x)=y_1(x)*ln(x) + another power series.
I am reluctant to do this for two reasons:
i) It does not seem logical that I should have to deal with two
power series when generating one solution.
ii) My suspicion is that there may exist a very efficient way to
generate both y_1(x) and y_2(x) using either an asymptotic expansion
or a rational function approximation, as holds true for Bessel
functions, which solve the above ODE when b=0.

Venkatakrishnan <venkat@icase.edu> Date: Wed, 14 Feb 1996 13:12:44 GMT Subject: ICASE/LaRC Workshop on Computational Fluid Dynamics ICASE/LaRC WORKSHOP ON BARRIERS AND CHALLENGES IN COMPUTATIONAL FLUID DYNAMICS August 5-7, 1996 Holiday Inn Hotel and Conference Center, Hampton, Virginia As a new millennium approaches, Computational Fluid Dynamics (CFD) is undergoing an important transition. CFD is playing an integral role in many inter-disciplinary applications. In addition, CFD techniques are increasingly being used in nontraditional areas such as material sciences and manufacturing technologies, and others. New algorithmic issues arise in such contexts and need to be addressed. At this time, therefore, it is particularly important to take an inward look and catalog the challenges that face the field and identify the barriers to be overcome. Numerical uncertainties need to be categorized and quantified so that they are not carried over to the new fields where we do not have years of experience to help us separate numerical uncertainties from physical uncertainties. In addition, techniques deemed inappropriate in CFD may well be the methods of choice when applied to new disciplines. For this workshop, papers are sought that: 1. help understand the nature of the problem 2. illustrate the effects of numerical uncertainties 3. quantify, alleviate or eliminate the barrier 4. identify new application areas requiring the use of CFD-based numerical methods 5. propose new algorithms to deal with emerging disciplines. It is expected that the papers presented will range from the scholarly to the practical and that the workshop will act as a catalyst for focussed research on reducing numerical uncertainties and for opening new avenues of research. This is meant to be a pioneering workshop conceived and organized in a way so as to maximize the effectiveness of the participation by the presenters and the audience. Invited talks will be 50 minutes long including 10 minutes for audience interaction. Contributed papers will be 25 minutes long including 5 minutes for audience interaction. Each session will include 30 minutes at the end of the session for a broader interactive participation by the audience and the panel of presenters. The themes emerging from such interactions will be collected and appended to the proceedings. The Workshop Technical Committee will work with the authors interactively and cooperatively to evolve the submitted material into a synergistic package so that papers in a session convey useful information, both individually and collectively. The tentative list of invited speakers is: 1. Alexandre Chorin - University of California, Berkeley 2. Michael Giles - Oxford University, UK 3. Roland Glowinski - University of Houston 4. Peter Lax - Courant Institute of Mathematical Sciences 5. Stanley Osher - University of California, Los Angeles 6. Philip Roe - University of Michigan, Ann Arbor Those interested in contributing should submit a two-page extended abstract for review by March 1, 1996. Submissions may be by hardcopy, e-mail or fax. Notifications of acceptance will be mailed out by March 22,1996.
