Let A = (A₁,...,An) and B = (B₁,...,Bn) be row contractions on Hilbert spaces 𝓗₁ and 𝓗₂, respectively, and L be a contraction from D B = ran ¯ D B to D A * = ran ¯ D A * where DB = (I – B*B)1/2 and ...

In this paper we offer a method for constructing functions with many gaps in their supports and in the supports of their Fourier transform. As a result we answer a question of Benedicks [Ben1] and we ...
