Filed under: General,Geometry — Tags: — m759 @ 11:00 AM

From a June 18 press release

KYOTO, Japan, Jun 18, 2010 (BUSINESS WIRE) — The non-profit Inamori Foundation (President: Dr. Kazuo Inamori) today announced that Dr. Laszlo Lovasz will receive its 26th annual Kyoto Prize in Basic Sciences, which for 2010 focuses on the field of Mathematical Sciences. Dr. Lovasz, 62, a citizen of both Hungary and the United States, will receive the award for his outstanding contributions to the advancement of both the academic and technological possibilities of the mathematical sciences.

Dr. Lovasz currently serves as both director of the Mathematical Institute at Eotvos Lorand University in Budapest and as president of the International Mathematics Union. Among many positions held throughout his distinguished career, Dr. Lovasz also served as a senior research member at Microsoft Research Center and as a professor of computer science at Yale University.

Global Game

Filed under: General — m759 @ 9:06 PM

Seymour Lazar, Flamboyant Entertainment Lawyer, Dies at 88

The New York Times  this evening has an obituary for Seymour Lazar, 
"Seymour the Head in Supermoney George Goodman’s 1972 account
of the global financial game, written under the pen name Adam Smith."

From that obituary —

"It was in Cuernavaca that Mr. Goodman, quite skeptical of the Lazar lore
he had heard so much of, met the man behind the myth. 'Seymour was
real,' he wrote…."

As is the Hungarian algorithm.

Mr. Lazar reportedly died on March 30. This journal on that date

Hungarian Algorithm

Filed under: General — Tags: — m759 @ 12:00 AM

“Of all the Hungarian friends I’ve ever had
I can’t remember one who didn’t want me to think of him
as a king of con men.”

” ‘The omelet, you know that, don’t you? Sure. It’s a classic.
An omelet, it’s in our Hungarian cookbook.
“To make an omelet,” it says “first, steal an egg.” ‘ ”

Cube Spaces

Filed under: General,Geometry — Tags: , , — m759 @ 11:30 AM

Cubic models of finite geometries
display an interplay between
Euclidean and Galois geometry.


Example 1— The 2×2×2 Cube—

also known as the eightfold  cube

2x2x2 cube

Group actions on the eightfold cube, 1984—


Version by Laszlo Lovasz et al., 2003—


Lovasz et al. go on to describe the same group actions
as in the 1984 note, without attribution.

Example 2— The 3×3×3 Cube

A note from 1985 describing group actions on a 3×3 plane array—


Undated software by Ed Pegg Jr. displays
group actions on a 3×3×3 cube that extend the
3×3 group actions from 1985 described above—

Ed Pegg Jr.'s program at Wolfram demonstrating concepts of a 1985 note by Cullinane

Pegg gives no reference to the 1985 work on group actions.

Example 3— The 4×4×4 Cube

A note from 27 years ago today—


As far as I know, this version of the
group-actions theorem has not yet been ripped off.

The Cube Space” is a name given to the eightfold cube in a vulgarized mathematics text, Discrete Mathematics: Elementary and Beyond, by Laszlo Lovasz et al., published by Springer in 2003. The identification in a natural way of the eight points of the linear 3-space over the 2-element field GF(2) with the eight vertices of a cube is an elementary and rather obvious construction, doubtless found in a number of discussions of discrete mathematics. But the less-obvious generation of the affine group AGL(3,2) of order 1344 by permutations of parallel edges in such a cube may (or may not) have originated with me. For descriptions of this process I wrote in 1984, see Diamonds and Whirls and Binary Coordinate Systems. For a vulgarized description of this process by Lovasz, without any acknowledgement of his sources, see an excerpt from his book.
