Strict qq-to-qq threshold conjecture for nonamenable quasi-transitive graphs

About 16 years old · traced to

Let GG be a connected, locally finite, quasi-transitive, nonamenable graph. For q∈(1,∞)q\in(1,\infty), let pq→q(G)p_{q\to q}(G) denote the qq-to-qq threshold used in the paper.

Strict qq-to-qq threshold conjecture. For every q∈(1,∞)q\in(1,\infty),

pc(G)<pq→q(G).p_c(G)<p_{q\to q}(G).

This is presented as a strengthening of the Benjamini–Schramm and triangle-condition conjectures. The paper notes that it is equivalent to pc<p2→2p_c<p_{2\to2} under the same hypotheses, while the general assertion remains open.
