Brent Abrahams
|
|
Corrected an attribution of
a quote; we had Gauss giving praise to Euler when it was LaPlace
instead, which lead us to explore the idea that Archimedes, Newton
and Gauss should stand alone among the great mathematicians, an idea
which we do not subscribe to.
|
| Moa Apagodu |
|
Corrected
an error we had in an explanation of the problems that arise using
Gosper's Algorithm. |
George Barker
|
|
Corrected an error in the page dealing
with the number of hands of poker.
|
Bo Brinkman
|
|
Communicated
the lovely Identity #3500009, which we haven't found in the literature
yet, so he may be the discoverer. (Knock on wood.) Bo also sent us
a .pdf file with an easy to follow proof of this identity.
|
Jonathan Burns
|
|
Corrected a sign error in Identity #3900015. Excellent!
|
| Vesselin
Dimitrov |
|
Sent in both
a factorization identity from Granville and several of his own.
|
Mark Eggensperger
|
|
Suggested
the inclusion of the pattern for turning a row of Pascal's Triangle
into a power of 11.
|
Bill Everett
|
|
Author of the paper about binomial coefficients divisible
by a fixed power of a prime.
|
| Ira Gessel |
|
Corrected
an error in the statement of Sperner's Theorem we had on the identities
page.
|
Martin P. Getz
|
|
Corrected an error in Identity #3100011. Our
first contributor from Alaska, to the best of my knowledge.
|
Nina Horne
|
|
Suggested a clarification of an unclear
point in the page on the uses of the binomial coefficients.
|
Gottfried Helms
|
|
Communicated
Identity #3500013, the natural log of the Pascal's Triangle matrix,
Identity #3900054, another matrix identity connecting the binomial
coefficients to the Delannoy numbers and Identity #390056, where
ex is given in a formula using binomial coefficients,
factorials and power series. He also has given us links to several
of his papers online.

Sean A. Irvine
|
|
Corrected
an error in Identity #3700004. Good on ya, Kiwis!
|
| Dan Jurca |
|
Communicated
Identity #5100007. |
| Dan Kalman
|
|
Communicated
the matrix identity #3900049. |
Pieter H. van der Kamp
|
|
Comunicated identities #2100003 and #2100004
and their hints, as well as identity #3610011.
|
| Isaiah
Lankham |
|
Sent in several
identities, most notably in the Factorization category. |
John L. Leonard
|
|
Sent in two
identities, #3700012 and #3700013, which are derived in the paper
"A Binomial Identity, via Derangements" by Chao, DesJarlais and
Leonard.

Kevin Marinelli
|
|
Helped us with the moving
of the website to another server when our original server left
campus. Thanks, Kevin!
|
Andrés Masegosa
|
|
Sent in the
identity #3100017, a generalization of Vandemonde's Convolution
he independently rediscovered. (Independently rediscovering
(relatively) well-known things is also a hobby of mine.)
|
| Russ
Merris |
|
Told me that
the name Christmas Stocking Theorem,
which I thought was common, was actually coined by
our mutual friend, the late Ken Rebman.
|
Chris Morgan
|
|
Suggested
including the information about B-splines and the binomial coefficients.
|
Augustine Munagi
|
|
Corrected
an error we had in Identity #3500004. Very keen observation.
|
Yogy Namara
|
|
Corrected
an error we had in Identity #1300002. Those darn plus and
minus signs!
|
Ron Ozer
|
|
Communicated Identity #1300004.
|
Angel Plaza
|
|
Communcated and proved Identity #3700015, and extension
of Identity #3500009, provided by Bo Brinkman. ¡Gracias, Angel!
|
Steven Poon
|
|
Communicated
Identity #3700014.
|
Sebastián Martín Ruiz
|
|
Corrected
an error in Identity #3900005 and communicated Identities #3610008,
#5100013, #3900053 and #2200004. ¡Gracias, Sebastián!
Also gave me the cool if inaccurate nickname "Todos Binomios".
|
Daniel Soll
|
|
Communicated
Identity #3400002, based on the coefficients from the Lucas polynomials;
we have not found elsewhere in the literature, and so he may be
the discoverer. As with Bo Brinkman above, we hope for the
best.
|
Stuart
P. Smith
|
|
Communicated
several identities from the Gradshteyn and Ryzhik book. |
| Jodi Soares |
|
She drew our
cool logo, based on vague suggestions from the author of the page. |
Zhi-Wei Sun
|
|
Added identities #3700007 and
#3700008.

Helped us with the moving
of the website to another server when our original server left
campus. Thanks, Rich!

Rick showed
a nice proof of Identity #2200002 in a class at UC Davis. |
