Subject: Preprint: A simple description of Thompson's group F
Date: Wed, 31 Aug 2005 14:37:39 +0100 [thread overview]
Message-ID: <1125495459.32083.3.camel@tl-linux.maths.gla.ac.uk> (raw)
The following paper is available:
"A simple description of Thompson's group F"
Marcelo Fiore, Tom Leinster
We show that Thompson's group F is the symmetry group of the "generic
idempotent". That is, take the monoidal category freely generated by an
object A and an isomorphism A \otimes A --> A; then F is the group of
automorphisms of A.

Incidentally, this is a result about groups, but the proof uses some
higher-dimensional category theory (multicategories, operads, and, less
essentially, bicategories).
