Title |
S-embeddings of planar graphs carrying the Ising model |
|
Abstract |
During the last decade, a number of results on conformal invariance of the critical planar Ising
model were obtained, both for correlation functions and collections of interfaces.
Nevertheless, in sharp contrast to random-walk based models, all these results remained
limited to 'nice' lattices and interaction constants (namely, to the Z-invariant Ising model on
isoradial graphs) until recently.
The main purpose of this talk is to discuss a new way of embedding weighted planar graphs
into the complex plane - s-embeddings - which plays the role of Tutte's barycentric
embedding for the critical Ising model. The technique developed so far allows to prove the
convergence of critical FK-Ising interfaces to SLE(16/3) on arbitrary periodic weighted graphs
and has a clear potential for generalizations. |
