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.

WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In the paper a condition equivalent to sparseness of a set is formulated. This condition is a base for a definition of a density point with respect to a family of sequences (C-density). It is shown that C-density is a generalization of a density with respect to one sequence (〈a〉 … WebA fixed lattice has the [n]-density property if n is large enough. 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.
