Kauffman‘s fixation on the work of Spencer-Brown is perhaps in part
due to Kauffman’s familiarity with Boolean algebra and his ignorance of
Galois geometry.  See other posts now tagged Boole vs. Galois.

"Geometric Group Theory" by Matt Clay, U. of Arkansas

"This article is intended to give an idea about how
the topology and geometry of a space influences
the algebraic structure of groups that act on it and
how this can be used to investigate groups."

Notices  homepage summary

A more precise description of the subject . . .

"The key idea in geometric group theory is to study
infinite groups by endowing them with a metric and
treating them as geometric spaces."

— AMS description of the 2018  treatise
Geometric Group Theory , by Drutu and Kapovich

See also "Geometric Group Theory" in this  journal.

The sort of thing that most interests me, finite  groups
acting on finite  structures, is not included in the above
description of Clay's article. That description only
applies to topological  spaces.  Topology is of little use
for finite  structures unless they are embedded* in 
larger spaces that are continuous, not discrete.

* As, for instance, the fifty-six 3-subsets of an 8-set are
embedded in the continuous space of The Eightfold Way .

Kaleidoscopic Structuralism…

Filed under: General — Tags: , , , — m759 @ 10:17 am

Continues.

"Think about anything often enough, from enough angles,
and it’s bound to splinter and refract. Our minds are like
kaleidoscopes, packed with mirrors we twist to see the
world anew. Sometimes we’re twisting consciously,
sometimes unconsciously. But no matter what, we end up
seeing patterns that are more a product of the tool in hand
than of the world on its other end."

—  Henry M. Cowles in The Los Angeles Review of Books , 
      October 11, 2022

Cowles on the book under review —

" Patrick House’s Nineteen Ways of Looking at Consciousness ,
a new book on neuroscience and its limits. Lest readers jump to
the wrong conclusion: The referent in House’s title, though also
poetic, is not Stevens but rather Nineteen Ways of Looking at
Wang Wei 
, an anthology of attempts to translate a four-line poem
from the Tang Dynasty."

"The referent" anthology is, according to Google Books

"a close reading of different translations of a single poem."

The close reader is Eliot Weinberger, who appeared here in 2011

my own work related to properties of the 4×6 rectangle above.
Symmetries of both the solids and the rectangle may be
viewed as permutations of  parts — In the Platonic solids,
the parts are permuted by continuous  rotations of space itself.
In the rectangle, the parts are permuted by non-continuous 
transformations, as in the I Ching . . . i.e., by concrete  illustrations

Bullshit Studies

— m759 @ 3:12 PM 

The essay excerpted in last night's post on structuralism
is of value as part of a sustained attack by the late
Robert de Marrais on the damned nonsense of the late
French literary theorist Jacques Derrida—

Catastrophes, Kaleidoscopes, String Quartets:
Deploying the Glass Bead Game

Part I:  Ministrations Concerning Silliness, or:
Is “Interdisciplinary Thought” an Oxymoron?

Part II:  Canonical Collage-oscopes, or:
Claude in Jacques’ Trap?  Not What It Sounds Like!

Part III:  Grooving on the Sly with Klein Groups

Part IV:  Claude’s Kaleidoscope . . . and Carl’s

Part V:  Spelling the Tree, from Aleph to Tav
(While  Not Forgetting to Shin)

The response of de Marrais to Derrida's oeuvre  nicely
exemplifies the maxim of Norman Mailer that

"At times, bullshit can only be countered
with superior bullshit."
