Abstract
We consider inhomogeneous non-oriented Bernoulli bond percolation on \(\mathbb {Z}^d\), where each edge has a parameter depending on its direction. We prove that, under certain conditions, if the sum of the parameters is strictly greater than 1/2, we have percolation in sufficiently high dimensions. The main tool is a dynamical coupling between models for different dimensions with different sets of parameters.
