In this paper we develop a theory of t-cycle D - Z representations for s-dimensional lattice rules of prime-power order. Of particular interest are canonical forms which, by definition, have a ...

AbstractLet M C =( A C 0 B )∈B(χ⊕χ) be an upper triangulat Banach space operator. The relationship between the spectra of 𝑀𝐶 and 𝑀₀, and their various distinguished parts, has been studied by a ...
