The London Algebra Colloquium
The London Algebra Colloquium is organized jointly between Imperial College and Queen Mary. A complete record of past Colloquia since 1950 is on Peter Cameron’s web page.

In the Summer term the Colloquium will be held at the Department of Mathematics, Imperial College. There is tea and coffee in the Common room from 4:15pm and the talks begin at 4:45pm in room 139. The programme is

More words
on words
In recent years
there has been extensive interest in
word maps on groups, and various results were obtained,
with emphasis on simple groups. We shall focus on some
new results on word maps for more general families of
finite and infinite groups.

Platonic
polygonal complexes
Examples of platonic polygonal complexes include the five regular solids, the tesselations of the
Euclidean and hyperbolic planes by regular polygons, and the 2-dimensional
faces of the
tesselation of each Euclidean space by equal cubes.
There are a lot more, and classifying
them all seems to be far too difficult.I shall
discuss recent joint work with
T. Januszkiewicz, R. Valle and R. Vogeler
in which we classify some families of these
complexes.

Reductive group schemes, Torsors, and Extended Affine Lie Algebras.
ABSTRACT: The theory of reductive groups over an
arbitrary base was developed
by Demazure and Grothendieck
in the early 60's. Affine (and extended affine)
Lie algebras were to appear later. About a decade ago a surprising relation
was found to exist between these two worlds. The bridge is given by torsors.
The talk, which will be for a general algebra audience, will illustrate the
concepts and ideas mentioned above.
