| Jan 16, 2011 at 22:07 | comment | added | user6976 | I can also add the PhD thesis of my former student Iva Spaculova. She studied the Ising model on groups with infinitely many ends, say, free groups (and arbitrary generating sets). It is more complicated (but somewhat similar) to percolation. See Iva's paper Špakulová, Iva, Critical percolation of virtually free groups and other tree-like graphs. Ann. Probab. 37 (2009), no. 6, 2262–2296. | |
