Query: Riesz Wavelets, Tiling and Spectral Sets in LCA Groups   This paper is devoted to the study of geometry properties of wavelet and
Riesz wavelet sets on locally compact abelian groups. The catalyst for our
research is a result by Wang ([32], Theorem 1.1) in the Euclidean wavelet
theory. Here, we extend the result to wavelet and Riesz wavelet collection of
sets in infinite locally compact abelian groups.
