Suppose k states form a union and every year a union chairman has to be selected in such a way that at any time the accumulated number of chairmen from each state is proportional to its weight. In… (More)

Let X be a non-empty set. Let f:Z2X. All vectors which occur have integer coefficients, and for =(a1,a2), =(b1,b2) we write or 0. A -block is a set of the form B(){Z2| 0 such that the -complexity of… (More)

Abstract Let f : Z → {0,1} be a given function. In 1938 , Morse and Hedlund observed that if the number of distinct vectors (f(x+1),…,f(x+n)) , x ∈ Z , called complexity, is at most n for some… (More)

Abstract A striking conjecture of Fraenkel asserts that every decomposition of Z >0 into m ⩾3 sets {⌊α i n+β i ⌋} n∈ Z >0 with α i and β i real, α i >1 and α i 's distinct for i =1,…, m satisfies {α… (More)

Abstract A Sturmian bisequence S is a subset of ℤ such that the numbers of elements of S in any two intervals of equal lengths differ by at most 1. A complementary triple of bisequences is a set of… (More)
