It is shown that a two-level orthogonal array with strength three whose run size is not a multiple of 16 has the hidden projection property that in its projection on to any five factors, all the main ...

Let K be a compact abelian group dual to a discrete abelian group which possesses an archimedean linear order. Let W = EH2(K) be a Beurling subspace of L2(K), where H2(K) is the space of analytic ...
