A Multidimensional Rado Theorem

We extend Deuber's theorem on $(m,p,c)$-sets to hold over the multidimensional positive integer lattices. This leads to a multidimensional Rado theorem where we are guaranteed monochromatic multidimensional points in all finite colorings of $\left(\mathbb{Z}^+\right)^d$ where the $i^{\mathrm{th}}$ set of coordinates satisfies the $i^{\mathrm{th}}$ given linear Rado system.
