Polynomial separation conjecture for capacitary holomorphic functions

Let V+V^+ be a complex neighborhood of the compact Riemann surface with boundary VV, let OVO\in V be the distinguished point, and let ϕ:V+C\phi:V^+\to\mathbb{C} be holomorphic with vanishing order ee at OO. Let σ\sigma be an antiholomorphic involution of V+V^+. Write ϕ[e](O)\phi^{[e]}(O) for the leading ee-th derivative data of ϕ\phi at OO, and let ϕ[e](O)V,Ocap,e\|\phi^{[e]}(O)\|^{\mathrm{cap},\otimes e}_{V,O} denote its capacitary norm.

Polynomial separation conjecture. If

logϕ[e](O)V,Ocap,e<0\log\|\phi^{[e]}(O)\|^{\mathrm{cap},\otimes e}_{V,O}<0

and ϕσ=ϕ\phi\circ\sigma=\overline{\phi} on V+V^+, then there exists a monic polynomial p(X)R[X]p(X)\in\mathbb{R}[X] such that

infxVp(1ϕ(x))>1.\inf_{x\in V}\left|p\left(\frac{1}{\phi(x)}\right)\right|>1.

This is the complex-analytic conjecture invoked in the paper's arithmetic theorem; its status is not resolved in the supplied material.
