Let K be any subset of $ℂ^N$. We define a pluricomplex Green's function $V_{K,θ}$ for θ-incomplete polynomials. We establish properties of $V_{K,θ}$ analogous to those of the weighted pluricomplex Green's function. When K is a regular compact subset of $ℝ^N$, we show that every continuous function that can be approximated uniformly on K by θ-incomplete polynomials, must vanish on $K∖supp(dd^{c} V_{K,θ})^N$. We prove a version of Siciak's theorem and a comparison theorem for θ-incomplete polynomials. We compute $supp(dd^{c} V_{K,θ})^N$ when K is a compact section.
