Two counterexamples, addressing questions raised in Adamczak (2019) and Poly and Zheng (2019), are provided. Both counterexamples are related to chaoses. Let Fn=Yn+Zn, where the random variables Yn and Zn belong to different chaoses of uniformly bounded degree. It may be that Fna.s.0, FnL2+δ0 and E{supn|Fn|δ}<, for some δ>0, and yet Yn fails to converge to 0 a.s.

关于和的几乎确定的收敛

提供了两个反例,以解决Adamczak(2019)和Poly和Zheng(2019)中提出的问题。两个反例都与混乱有关。让Fñ=ÿñ+žñ,其中随机变量 ÿñžñ属于统一界度的不同混沌。可能是Fñ一个s0Fñ大号2+δ0Ë{SUPñ|Fñ|δ}<, 对于一些 δ>0, 但是 ÿñ 未能收敛为0
