Abstract
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 Fn⟶a.s.0, Fn⟶L2+δ0 and E{supn|Fn|δ}<∞, for some δ>0, and yet Yn fails to converge to 0 a.s.
