Kraljević [Elektronische Daten] [Miljenko Crnjac, Boris Guljaš, Harry Miller] Summary: In this paper, assuming a certain set-theoretic hypothesis, a positive answer is given to a question of H. Kraljević, namely it is shown that there exists a Lebesgue measurable subsetA of the real line such that the set {c ∈ R: A + cA contains an interval} is nonmeasurable. Here the setA + cA = {a + ca′: a, a′ ∈ A}. Two other results about sets of the formA + cA are presented.
