Normality equivalence conjecture for deterministic dynamically generated basic sequences

About 1 year old · traced to

Let Q=(qn)n≥1Q=(q_n)_{n\geq 1} be a deterministic dynamically generated basic sequence. Write N(Q)\mathcal{N}(Q) for the set of QQ-normal numbers, UN(Q)\mathcal{UN}(Q) for the uniformly QQ-normal numbers, UDN(Q)\mathcal{UDN}(Q) for the uniformly distribution-normal numbers, and DN(Q)\mathcal{DN}(Q) for the distribution-normal numbers. Normality equivalence conjecture.

N(Q)=UN(Q)=UDN(Q)=DN(Q).\mathcal{N}(Q)=\mathcal{UN}(Q)=\mathcal{UDN}(Q)=\mathcal{DN}(Q).

This conjecture would unify the principal normality notions for deterministic dynamically generated basic sequences; the preceding text says that the hotspot conjecture would imply it, while the full equivalence remains open.
