一个与黄金比例近似值有关的整函数

An entire function connected with the approximation of the golden ratio

Anton A. Kutsenko

摘要:

1987年,R. B. Paris使用解析函数\[\label{main} g(w)=\lim_{n\to\infty}(2φ)^n\biggl(\underbrace{\sqrt{1+\sqrt{1+...\sqrt{1+w}}}}_n-φ\biggr),\ \ \ φ=\frac{1+\sqrt{5}}2, \]来估计嵌套平方对黄金分割率的收敛性。函数$g$是非完整的,并且可能不能用某些标准的已知函数来表示。证明了$f(z):=g^{-1}(z)$是一个满足Poincare等式的整函数.虽然$f$有各种多重性的零点,但它可以用它的单零点来表示,形成类似于朱利亚集的分形结构。

英文摘要:

In 1987, R. B. Paris uses the analytic function \[\label{main} g(w)=\lim_{n\to\infty}(2φ)^n\biggl(\underbrace{\sqrt{1+\sqrt{1+...\sqrt{1+w}}}}_n-φ\biggr),\ \ \ φ=\frac{1+\sqrt{5}}2, \] to estimate the convergence of nested squares to the golden ratio. The function $g$ is non-entire and, perhaps, can not be expressed in terms of some standard known functions. We show that $f(z):=g^{-1}(z)$ is an entire function satisfying Poincare equality. While $f$ has zeros of various multiplicities, it can be expressed in terms of its simple zeros, forming fractal structures similar to Julia sets.
