NY‑Valdivia status of continuous images of A(ω1)^ω

Determine whether every continuous image of the countable product A(ω1)^ω, where A(ω1) is the one‑point compactification of a discrete space of cardinality ω1, is an NY‑Valdivia compact space (i.e., admits an embedding into a product of Hilbert cubes ∏ Q_y such that the σ‑product σ(∏ Q_y) is dense in the image).

Background

The paper shows that uniform Eberlein compact spaces need not be NY‑Valdivia by exhibiting K = AD(A(ω1)ω) as a counterexample. Since every uniform Eberlein compact space is a continuous image of a closed subspace of A(κ)ω, this naturally leads to asking about the NY‑Valdivia status of continuous images specifically of A(ω1)ω.

The question focuses on whether the NY‑Valdivia property is preserved under taking continuous images of the canonical product built from the one‑point compactification of a discrete uncountable space, a theme connected to polyadic spaces and their invariants.
