The other bullets in the record concern prime partitions and the growth of the least squarefree local period; they are distinct questions and are not conjoined with this root. Quantifying only a≥1 makes inclusion of 0 in the ambient representability predicate immaterial.
Scope. The set of positive natural numbers representable as x^2+y^2 with natural x and y; an unrestricted positive translation may depend on n.
