Subject: Distribution of Eigenvalues
To NA Readers:
Does anyone know a good reference for the following problem?
Given a stochastic nxn matrix and its distribution function, what is the
distribution of the eigenvalues and eigenvector. In particular,
what is the distribution of the Perron root and the Perron right and
left eigenvectors of this matrix.
I would greatly appreciate any help in tracking down references in
this area. Please respond either through NA-Net or directly to:
HARKER@wharton.upenn.edu
Thanks.

Subject: Finding Interior Eigenvalues
EIGENVALUE SOLVER NEEDED
Matrix A has real non-zero eigenvalues only.
Does anyone have an efficient algorithm for
finding the two eigenvalues (positive and negative)
which are closest to the origin?
The algorithm should not involve inverting of the
matrix A itself.
Many thanks.

Subject: SIAM Membership List from NETLIB
Netlib now lets you search the SIAM membership list. Say
mail netlib@anl-mcs.arpa (or mail research!netlib)
who is Ed Block
and in reply you should get an address and phone number.
This is not to be used for mass mailings, etc. (To enforce that, netlib
limits the size of replies.) If you're not on the list, send mail to
siam@wharton.upenn.edu; they'll be happy to tell you how to join.
In the past, netlib looked in a database maintained by Gene Golub and
Mark Kent. The new default should be more complete and current, since
people on the move usually remember to have their journals follow.
Still, Gene's list may have more information, for example about
electronic addresses and home phone numbers. To search it instead, say
mail netlib
who is Block from golub.
Problems and suggestions may be directed to Eric Grosse, ehg@att.arpa,

Subject: 1988 ODE Meeting at Toronto
Final Announcement and Call for Papers for
The 1988 Conference on the Numerical Solution of IVPs for ODEs
to be held 20-24 June 1988 at the University of Toronto
Organized by
Professors Wayne Enright and Ken Jackson,
Department of Computer Science, University of Toronto,
Toronto, Ontario, Canada, M5S 1A4.
(enright@csri.toronto.edu or krj@csri.toronto.edu)
This is the final announcement and call for papers for The 1988
Conference on the Numerical Solution of Initial-Value Problems for
Ordinary Differential Equations to be held 20-24 June 1988 in the
Department of Computer Science at the University of Toronto. To
facilitate travel arrangements, the conference will close at noon of
the final day. The language of the conference will be English.
The previous conference in this series was held in Albuquerque
in July of 1986, and its programme included talks on both Initial-
Value Problems (IVPs) and Boundary-Value Problems (BVPs) for
Ordinary Differential Equations (ODEs). Because of the large number
of researchers working in these two areas and the modest number of
them active in both fields, we chose to emphasize IVPs at the
Toronto meeting, although talks related to BVPs with a significant
IVP content will not be excluded.
There will be both 50-minute invited lectures and 30-minute
contributed talks at the Toronto meeting. In addition, there will
be ample time for informal discussion with colleagues. We are
pleased to announce that the following distinguished researchers
have accepted our invitation to speak at the conference:
J. C. Butcher, P. Deuflhard, J. Dormand and P. J. Prince,
C. W. Gear, R. Jeltsch, S. P. Norsett, and L. F. Shampine. We hope
to attain a balance between the practical and theoretical aspects
associated with the numerical solution of IVPs for ODEs in the talks
at this conference. In part, the invited speakers were chosen with
this in mind.
We encourage participants to submit (preferably with their
conference registration) a title, list of authors and their
addresses, and abstract for a 30-minute contributed talk. These
should be written in English, single spaced, at most one page in
length, and suitable for photo-copying onto 8.5 by 11 inch paper for
distribution in the form of a technical report to conference
participants. No other form of publication is planned for this
meeting. To enable us to inform authors by 1 May 1988 whether their
paper has been accepted for presentation at the conference, the
deadline for receiving titles and abstracts is 18 March 1988.
By holding the meeting on the university campus, we have
attempted to keep the conference registration fee to a minimum.
However, please note that to take advantage of this, you must
register before 13 May 1988. To do so, print and complete the
enclosed form and mail it together with your registration fee to the
address listed thereon. (Do not e-mail the form to me without
payment.) We have reserved a block of reasonably-priced rooms at one
of the university residences, a short walk of about 100 meters from
the conference site. To reserve a room, print and complete the
enclosed form and mail it together with your room deposit to the
address listed thereon. (Again, do not e-mail the form to me
without payment.) For those who prefer less Spartan accommodation,
we have reserved a block of rooms at the Delta Chelsea Inn in
downtown Toronto, about one kilometer from the conference site.
Please find enclosed directions for making room reservations at the
Inn. Although we believe that we have booked a sufficient number of
rooms, please reserve early to avoid disappointment.
We hope that there will be some funds available to defray the
expenses of those with limited or no travel support. To apply for
such assistance, include a letter with your registration form
detailing the amount of assistance you require from us, and send
your completed residence room reservation form to us rather than
directly to Residence Services. Preference will be given to those
applicants who will speak at the conference. We will hear by about
mid March how large a grant we have been awarded. As soon as
possible thereafter, we will inform you whether we are able to
provide any travel assistance to you.
This is the final general announcement for this conference.
Further information will be sent to registrants only.
Please circulate this announcement to interested colleagues.

If the results have been contributed to the public domain, could someone
post them to this newsgroup? I would guess that most subscribers would
be very interested in the results. (If not, would you email me a copy, too?)

Subject: Report on a Conference in Nigeria
Conference in Computational Mathematics, Benin City, Nigeria,
Jan 25 - 29 1988, organized by Simeon Ola Fatunla of the
University of Benin.
I hesitated quite a lot before accepting the invitation to this
conference. Many more or less bad stories about Nigeria
had been brought to my attention. Today I just wanted to tell
everybody the extremely good experience we had. From outside
of Africa the following people attended the conference:
G. Corliss, Guo Ben-Yu, G. Hall, P. Kaps, J. D. Lambert,
R. Mattheij, J.D. Pryce, J.N. Sanz-Serna, A. Shidfar
and myself. The Nigerian people took extremely good
care of us, were very helpfull and made our stay a very
pleasant one. The moment we passed the passport control
at Lagos International Airport, we were met by a university
official who helped us to make the connections to the
continuation flight to Benin City, or we could have been driven
directly to Benin City. In Benin City again S. Fatunla and his staff
cared for us the whole time until we were finally seen off at
Lagos International Airport.
Professional problems which our collegues in Nigeria have to
face are huge -- like no journals since 1981, power breakdowns
approximately once a day (the computer centre has a whole
room of batteries to keep the current steady), poor communications
and so on. One can not help but admire the way our collegues
fight against all these circumstances.
This message is just to ask everybody to help our collegues in
Nigeria whenever possible. Prof. J.O. C. Ezeilo of the University
of Nsukka, Nigeria, (President of the Nigerian Mathematical Society)
is building up a Mathematics Center funded by the federal
Governement. He is looking for possible cooperation with
the mathematicians from outside Nigeria.
If anybody wants to get futher information please let me know or
contact one of the above mentioned participants.

Subject: Motorola MC68881/MC68882 manual published by Prentice Hall
I just received a copy of this manual, copyright by Motorola but
published by Prentice Hall, so that, like the MC68020 manual,
it may actually be obtainable in technical bookstores rather
than by begging a Motorola sales office. At last there will
be an answer for people that I've told to read a 68881 manual
without telling them how to obtain it.
The MC68881 is the best hardware implementation of IEEE arithmetic
from the standpoint of completeness and correctness, except for
some minor complaints:
transcendental functions are not monotonic in extended precision,
log2(x) and 2**x aren't exact in some places they could be,
there are no fmove-out instructions that round the source
f register to the stored value
not all the information that a user trap handler could exploit
is available in user mode
Transcendental functions are guided by the spirit rather than the
specification of the IEEE standard, anyway, and most other hardware
implementations don't come close.
CISC enthusiasts should compare the 68881/2 instruction set to
anything similar they may have been using to see the difference a
clean orthogonal instruction set can make.
RISC enthusiasts don't care about on-board transcendentals because,
by their own admission, they are smart enough to code them faster
using a smaller instruction set. They would be well advised,
in general, not to be too pleased with their results
until they are reasonably close to the 68881's in accuracy.
I don't know whether or not to be surprised, but the page layout
produced by Prentice Hall is not as aesthetically pleasing as that
of the 68881 manual published by Motorola.

Subject: SIAM Annual Meeting in Minneapolis
SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS
MEETING ANNOUNCEMENT AND CALL FOR PAPERS
SIAM Annual Meeting and Short Course
Hyatt Regency Hotel, Minneapolis, Minnesota
July l0-l5, l988
DIRECTIONS IN APPLIED MATHEMATICS
Agenda for the Future
The organizers of the SIAM l988 Annual Meeting are planning a program
on evolving areas of applied mathematics and related topics that should
provide new opportunites for research and problem solving in the decade ahead.
Prizes to be awarded at the l988 SIAM Annual Meeting:
The George B. Dantzig Prize
The prize is awarded jointly by the Mathematical Programming Society (MPS) and
SIAM. It is awarded for original work which by its breadth and scope
constitutes an outstanding contribution to the field of mathematical
programming.
The Dantzig Prize is awarded every three years and, while normally presented
at the International Symposium of MPS, it will be awarded for the first time
at this SIAM meeting.
The Richard C. DiPrima Prize
The Richard C. DiPrima Prize was established in l986 to commerorate the former
president of SIAM who also served for many years as a member of the SIAM
Council and Board of Trustees, as Vice President for Programs, and as a
dedicated and committed member.
The prize is awarded to a young scientist who has done outstanding research in
applied mathematics and who has completed his/her doctoral dissertation and
completed all other requirements for his/her doctorate during the period
running from three years prior to the award date to one year prior to the
award date.
This will be the first awarding of this prize which is scheduled to be given
every even year.
The John von Neumann Lecture and Prize
The lecturer will survey and evaluate a significant and useful contribution to
mathematics and its applications. The prize may be awarded to a mathematician
or to a scientist in another field but, in either case, the recipient should
be one who has made distinguished contriubtions to pure and /or applied
mathematics.
