We construct two planar homoeomorphisms $f$ and $g$ for which the origin is a globally asymptotically stable fixed point whereas for $f \circ g$ and $g \circ f$ the origin is a global repeller. Furthermore, the origin remains a global repeller for the iterated function system generated by $f$ and $g$ where each of the maps appears with a certain probability. This planar construction is also extended to any dimension $>$2 and proves for first time the appearance of the dynamical Parrondo's paradox in odd dimensions.

Parrondo 的同胚悖论

我们构造了两个平面同胚$f$$g$,它们的原点是一个全局渐近稳定不动点,而对于$f\circ g$$g\circ f$,原点是一个全局排斥器。此外,原点仍然是由$f$$g$生成的迭代函数系统的全局排斥器,其中每个映射以一定的概率出现。这种平面结构也扩展到任何维度$>$ 2,并首次证明了动力帕隆多悖论在奇数维度中的出现。
