Query: Almost universality of a sum of norms   In this paper the author considers a particular type of polynomials with
integer coefficients, consisting of a perfect power and two norm forms of
abelian number fields with coprime discriminants. It is shown that such a
polynomial represents every natural number with only finitely many exceptions.
The circle method is used, and the local class field theory plays a central
role in estimating the singular series.
