Schinzel's bounded orthogonal relation conjecture

Let F,GZ[x1,,xn]F,G\in \mathbb{Z}[x_1,\dots,x_n] be relatively prime. Let a:=(a1,,an)Zn{\bf a}:=(a_1,\dots,a_n)\in\mathbb{Z}^n and let ξQ\xi\in\overline{\mathbb{Q}}^* be not a root of unity. Suppose that

F(ξa1,,ξan)=G(ξa1,,ξan)=0.F(\xi^{a_1},\dots,\xi^{a_n})=G(\xi^{a_1},\dots,\xi^{a_n})=0.

Schinzel's conjecture. There exists a nonzero vector bZn{\bf b}\in\mathbb{Z}^n orthogonal to a{\bf a} such that

bB(F,G),\lVert{\bf b}\rVert_{\infty}\leq B(F,G),

where B(F,G)>0B(F,G)>0 depends only on FF and GG. The conjecture predicts a uniformly bounded multiplicative relation among the exponents whenever the two relatively prime polynomials vanish at the corresponding powers of a non-torsion algebraic number. The paper's abstract states that it gives a new proof of this conjecture and an explicit result depending on the height and degree of the variety, so the parser's unknown status should be checked against the paper's resolution.
