Our main result, Theorem1below, establishes a strong form of the density hypothesis for natural broad \horizontal" families of arithmetic lattices, arising from all suitable division quaternion algebras over varying number elds.

WebAbstract. For a given set M of positive integers, a well-known problem of Motzkin asked to determine the maximal asymptotic density of M-sets, denoted by (M), where an M-set is a set of non-negative integers in which no two elements di er by an element in M. In 1973, Cantor and Gordon found (M) for jMj 2.

The density of a generator U of a union-closed family of sets L containing the empty set is estimated. The estimate depends only on the local properties of L at U. If L is generated by sets of size at most two, then there is a generator U of L with estimated density at most 1/2.
