What's behind the background?
It's a picture I generated as part of a project with
Alessandra Iozzi investigating
algebraic compactifications of SL(2,R). The small regions are
fundamental domains for the action of the symmetric group S5
on (a subset of) R2, and the colored numbers tell which
permutations move which sides where. The quotient space is the moduli space
of algebraic compactifications of SL(2,R) which lie in the
five-dimensional torus T5.
Here is a clearer image:
A couple of the papers on my [p]reprints page
are related to this project -- the ones with "boundary compactifications" in
the title.
