Continuity of percolation probability on hyperbolic graphs

  • C. Chris Wu
Short Communications


LetT k be a forwarding tree of degreek where each vertex other than the origin hask children and one parent and the origin hask children but no parent (k≥2). DefineG to be the graph obtained by adding toT k nearest neighbor bonds connecting the vertices which are in the same generation.G is regarded as a discretization of the hyperbolic planeH2 in the same sense thatZ d is a discretization ofR d . Independent percolation onG has been proved to have multiple phase transitions. We prove that the percolation probabilityO(p) is continuous on [0,1] as a function ofp.
