Audit review
The paper’s principle works by allowing a controlled deformation of the complex/symplectic structure and proves realizations via J-holomorphic extensions on a complexification, then invokes uniqueness of real-analytic symplectic structures. The candidate solution attempts to run AbC entirely within the canonical real-analytic symplectic category by asserting a density of analytic maps in the centralizer of rational rotations with uniform holomorphic extension to a fixed complex neighborhood. This density claim contradicts the paper’s highlighted rigidity (analytic entire extensions on the cylinder must be shears) and is not justified for large complexifications. Key analytic/complex-domain control and exact centralizer constraints are missing, so the model’s proof does not go through, whereas the paper’s argument is coherent and complete.
Referee report (LaTeX)
\textbf{Recommendation:} minor revisions \textbf{Journal Tier:} strong field \textbf{Justification:} The paper provides a sound and innovative principle enabling analytic AbC realizations on surfaces by sidestepping a genuine rigidity in the canonical analytic category. The structure-deformation approach is carefully executed and broadly applicable. Minor clarifications contrasting the approach with tempting but invalid direct methods would strengthen accessibility.
