The Laplace-transform formulation of the Image Conjecture

Let M{\mathcal M} be the subspace of polynomials f(ξ,z)C[ξ,z]f(\xi,z)\in{\mathbb C}[\xi,z] such that Z(f){\mathcal Z}(f) has no holomorphic part, equivalently such that the Laplace transformation L(f)(ξ){\mathcal L}(f)(\xi) has no ξ[1]C[ξ1]\xi^{[-1]}{\mathbb C}[\xi^{-1}]-part. The Laplace-transform formulation of the Image Conjecture. For any f(z),g(z)C[ξ,z]f(z),g(z)\in{\mathbb C}[\xi,z] with fmMf^m\in{\mathcal M} for every m1m\geq1, one has fmgMf^m g\in{\mathcal M} for all sufficiently large mm.

This is presented as a restatement of the image conjecture using the preceding description of ImΘ\operatorname{Im}\Theta and the multidimensional Laplace transformation. It is therefore not a new independent conjecture, but a reformulation of the preceding image conjecture.
