Equality of critical parameters for loop and Bernoulli percolation at diverging degree
Let be a sequence of finite, connected, vertex-transitive graphs with vertex degree diverging as . For a fixed sequence and fixed , define
and
whenever the limits are well-defined, and set , , and . Critical-parameter equality conjecture. If and exist, then for every ,
The conjecture proposes that, even when the vertex degree diverges, the loop-percolation critical parameter agrees with the corresponding Bernoulli-percolation parameter. The source gives no resolution, and the vertex-transitivity assumption is explicitly not expected to be necessary.
