摘要：
We investigate what happens to the third order ferromagnetic phase transition displayed by the Ising model on various dynamical planar lattices (i.e. coupled to 2D quantum gravity) when we introduce annealed bond disorder in the form of either antiferromagnetic couplings or null couplings. We also look at the effect of such disordering for the Ising model on general phi3 and phi4 Feynman diagrams.
