Abstract

We study atomic measures on [0,1][0,1] which are invariant both under multiplication by 2mod12\mod 1 and by 3mod13\mod 1, since such measures play an important role in deciding Furstenberg's ×2,×3\times 2, \times 3 conjecture. Our specific focus was finding atomic measures whose supports are far from being uniformly distributed, and we used computer software to discover a number of such measures (which we call \emph{outlier measures}). The structure of these measures indicates the possibility that a sequence of atomic measures may converge to a non-Lebesgue measure; likely one which is a combination of the Lebesgue measure and one or more atomic measures.
