Abstract

The star-triangle transformation was discovered in 1899. It has since
become one of the basic tools for studying disordered systems in two
dimensions, and it is known amongst physicists as the `Yang-Baxter
equation'. We shall explain its harmony with de Bruijn's theory of
tilings and isoradial graphs, as developed by Kenyon and co-authors.
Then we outline its use in proving universality for percolation in two
dimensions. (joint work with Ioan Manolescu)
