Английская Википедия:Feigenbaum's second constant
Материал из Онлайн справочника
The second Feigenbaum constant or Feigenbaum's alpha constant Шаблон:OEIS,
- <math>\alpha = 2.502\,907\,875\,095\,892\,822\,283\,902\,873\,218...,</math>
is the ratio between the width of a tine and the width of one of its two subtines (except the tine closest to the fold). A negative sign is applied to Шаблон:Math when the ratio between the lower subtine and the width of the tine is measured.[1]
These numbers apply to a large class of dynamical systems (for example, dripping faucets to population growth).[1]
A simple rational approximation is Шаблон:Sfrac × Шаблон:Sfrac × Шаблон:Sfrac = Шаблон:Sfrac.
