我们给出一维Fock空间中高斯点处平方限制形式的局部稳定相位检索的简短复分析证明。主要估计是映射 $F\mapsto F^2$ 的强制性不等式:$\\|F^2-F(0)^2\\|_{\mathcal{F}^2(\mathbb{C})} \lesssim \inf_{c\in\mathbb{R}}\\||F|^2-c\\|_{L^2(d\gamma)}$。证明使用加权导数范数、两次分部积分和加权柯西不等式,且已借助大语言模型在Lean中完成完全验证。
英文摘要
We give a short complex-analytic proof of a square-restricted form of local stable phase retrieval at the Gaussian in one-dimensional Fock space. The main estimate is a coercivity inequality for the map $F\mapsto F^2$: \[ \|F^2-F(0)^2|_{\mathcal{F}^2(\mathbb{C})} \lesssim \inf_{c\in\mathbb{R}}\||F|^2-c\|_{L^2(d γ)}. \] The proof uses a weighted derivative norm, two integrations by parts, and a weighted Cauchy inequality. The proof has been completely verified in Lean with the aid of Large Language Models.
