我们对3-非交叉骨架匹配的生成函数以及正则3-非交叉骨架图进行了完整且严格的渐近分析。设$F_3$为3-非交叉匹配的普通生成函数，设$S(y)=\u03a3_{n\u22650}S(n)y^n$由$S(zF_3(z)^2)=F_3(z)$确定。证明刻意按顺序排列以避免循环：首先，利用拉格朗日反演、$F_3$的斯蒂尔杰斯表示、精确割边界估计以及移动水平汉克尔轮廓，得到$S(n)\u223c24(\u03c0 A^5)^{-1}\u03c3^{-n}n^{-5}$，且该结果与$S$的任何$\u0394$-解析性无关；此估计提供了$S$和$S'$的边界正则性。随后，我们证明全局全纯反演定理、收敛圆的每个非主点处的延拓以及对数扰动扇形反演定理；完整的圆盘链和单值性论证得到标准$\u0394$-域上的单值延拓。在主奇点处，$S(y)=Q_4(u)-(\u03c0 A^5)^{-1}u^4\boldsymbol{\textrm{log}}u+O(u^5(1+|\boldsymbol{\textrm{log}}u|))$，其中$u=1-y/\u03c3$。最后，证明正则复合$S_3^{[4]}(z)=(1-z)(S(\u03d1(z))-1-\u03d1(z))$在其唯一主奇点$\u03b7=0.49340718057613087519\boldsymbol{\textrm{…}}$处是$\u0394$-解析的，且$[z^n]S_3^{[4]}(z)\u223c7892.16205\boldsymbol{\textrm{ }}625817\boldsymbol{\textrm{…}}n^{-5}\u03b7^{-n}$。该论证保留了原始证明的方法和详细估计，同时弥补了早期学位论文处理中的分析缺口。
英文摘要
We give a complete rigorous asymptotic analysis of the generating functions of 3-noncrossing skeleton matchings and canonical 3-noncrossing skeleton diagrams. Let $F_3$ be the ordinary generating function of 3-noncrossing matchings, and let $S(y)=\sum_{n\geq 0}S(n)y^n$ be determined by $S(zF_3(z)^2)=F_3(z)$. The proof is deliberately ordered to avoid circularity. First, Lagrange inversion, a Stieltjes representation of $F_3$, exact cut-boundary estimates, and a moving horizontal Hankel contour give $S(n)\sim 24(πA^5)^{-1}σ^{-n}n^{-5}$ independently of any $Δ$-analyticity of $S$. This estimate supplies boundary regularity of $S$ and $S'$. We then prove a global biholomorphic inversion theorem, continuation across every nonprincipal point of the convergence circle, and a logarithmically perturbed sectorial inverse theorem. A complete disk-chain and monodromy argument yields a single-valued continuation to a standard $Δ$-domain. At the principal singularity, $S(y)=Q_4(u)-(πA^5)^{-1}u^4\log u+O(u^5(1+|\log u|))$, where $u=1-y/σ$. Finally, the canonical composition $S_3^{[4]}(z)=(1-z)(S(\vartheta(z))-1-\vartheta(z))$ is shown to be $Δ$-analytic at its unique dominant singularity $η=0.49340718057613087519\ldots$, and $[z^n]S_3^{[4]}(z)\sim 7892.16205625817\ldots n^{-5}η^{-n}$. The argument retains the methods and detailed estimates of the original proofs while closing the analytic gaps in the earlier dissertation treatment.
