    We prove that if 2 ≤ k1 ≤ k2, then there is no infinite sequence $\emph{A}$ of positive integers such that the representation function r(n)=#{(a, a'): n=$k{_1}a$ + $k{_2}a'$, a,a' ∊ $\emph{A}$} is constant for n large ...

  • The least common multiple of random sets of positive integers 

    Cilleruelo, Javier; Rué Perna, Juan José; Sarka, Paulius; Zumalacárregui, Ana (2014-11-01)
    Open Access
    We study the typical behavior of the least common multiple of the elements of a random subset A¿{1,…,n}. For example we prove that lcm{a:a¿A}=2n(1+o(1)) for almost all subsets A¿{1,…,n}
