Coordinatewise monotonicity of connectivity on the integer lattice
Let and . On the graph , whose vertices at Euclidean distance are joined by an edge, use the componentwise order defined by for every . Coordinatewise monotonicity conjecture. For Bernoulli percolation with parameter ,
This folklore conjecture is trivial for but remains open already for ; a partial result establishes it along coordinate axes when is sufficiently close to .
