DESCRIPTION:Graphical representations of the Ising model have been tremend
 ously successful for both simulations and rigorous results. These represen
 tations are coupled to each other using the uniform even subgraph operatio
 n\, which is invariant under XOR. Using intution about the ground state of
  the toric code this trick enables simple proofs of equality of critical p
 oints of the loop O(1)  and Ising models and exponential decay for the two
 -dimensional near-critical model. The scaling limit of the latter is famou
 sly conjectured to be related to the exceptional Lie Algebra E_8. \n\nJoin
 t work with Ulrik Hansen\, Jiangping Jiang and Peter Wildemann.
