Strict asymptotic enhancement of three-fluid center percolation

About 7 years old · traced to

Let MnM_n be the finite honeycomb-lattice region, let OO be its central cell, and let Ak,n⊂ΩA_{k,n}\subset\Omega be the event that fluid kk, for k=1,2,3k=1,2,3, percolates from OO to the boundary of MnM_n. Asymptotic enhancement conjecture.

lim⁡n→+∞P(A1,n∩A2,n∩A3,n)P(A1,n)P(A2,n)P(A3,n)>1.\lim_{n\to+\infty}\frac{P(A_{1,n}\cap A_{2,n}\cap A_{3,n})}{P(A_{1,n})P(A_{2,n})P(A_{3,n})}>1.

This conjecture is stronger than finite-scale positive correlation: it predicts a strictly nontrivial limiting enhancement of the joint probability. The paper gives informal arguments in its favor but does not prove it.
