AbstractFor an expanding integral s x s matrix A with \det A\ = p, it is well known that if D = {d(0),...,d(p-1)} subset of Z(s) is a complete set of coset representatives of Z(s)/AZ(s), then T(A, D) is a self-affine tile. In this paper we show that if p is a prime, such D actually characterizes the tile digit sets provided that span(D) = R-s. This result is known for s = 1. the one-dimensional case [R. Kenyon, in: Contemp. Math., vol. 135, 1992, pp. 239-264] and the question for s > 1 has been considered by Lagarias and Wang [J. London Math. Soc. 53 (1996) 21-49] under some other conditions. The proof here involves a new setup to study the zeros of the mask m(xi) = p(-1) Sigma(j=0)(p-1) e(2pii(xi,d j)). It can also be generalized to consider the existence of a compactly supported L-1 -solution of the refinement equation (scaling function) with positive coefficients.
