Wilkie's local definability conjecture for holomorphic functions

About 9 years old · traced to

Let A\mathcal{A} be a family of complex holomorphic functions. Let z∈Cnz\in\mathbb{C}^{n}, let UU be an open neighbourhood of zz, and let f:U→Cf:U\rightarrow\mathbb{C} be holomorphic and locally ∅\emptyset-definable in RA↾\mathbb{R}_{\mathcal{A\upharpoonright}}. Let PG\mathcal{P}_{G} denote the family of polynomials with Gaussian rational coefficients. Wilkie's conjecture. There is an open box with Gaussian rational corners Δ⊆U\Delta\subseteq U such that z∈Δz\in\Delta and f↾Δf\upharpoonright\Delta can be obtained from A∪PG\mathcal{A}\cup\mathcal{P}_{G} by finitely many applications of composition, Schwarz reflection, taking partial derivatives, and extracting implicit functions.

The conjecture proposes a uniform complex-analytic description of locally definable holomorphic functions, extending Wilkie's generic-point result to every point. The paper's introduction states that this description is not complete around non-generic points, so the conjecture is refuted by the results of the paper.
