Exponential estimates conjecture for the contact process in dynamic percolation

Let (C,B)(\mathbf{C},\mathbf{B}) be a contact process in dynamic percolation (CPDP) with rates λ,r,α,β>0\lambda,r,\alpha,\beta>0 on the dd-dimensional integer lattice. Let θDP(λ,r,α,β)\theta_{\mathrm{DP}}(\lambda,r,\alpha,\beta) denote its survival probability.

Exponential estimates conjecture. If

θDP(λ,r,α,β)>0,\theta_{\mathrm{DP}}(\lambda,r,\alpha,\beta)>0,

then there exist constants C1,C2,M>0C_1,C_2,M>0 such that the three conditions labelled ConjectureEq1\mathrm{ConjectureEq1}, ConjectureEq2\mathrm{ConjectureEq2} and ConjectureEq3\mathrm{ConjectureEq3} in the source are fulfilled.

These estimates are the hypotheses used to derive the asymptotic shape theorem. Comparable estimates have been proved for the contact process in a static random environment and for the contact process with ageing; proving them for the CPDP would extend those methods to this dynamical setting.
