  text: ' matching is compatible to two or more labeled point sets of size n with
    labels   {1,…,n}  if its straight-line drawing on each of these point sets is
    crossing-free. We study the maximum number of edges in a matching compatible to
    two or more labeled point sets in general position in the plane. We show that
    for any two labeled convex sets of n points there exists a compatible matching
    with   ⌊2n−−√⌋  edges. More generally, for any   ℓ  labeled point sets we construct
    compatible matchings of size   Ω(n1/ℓ) . As a corresponding upper bound, we use
    probabilistic arguments to show that for any   ℓ  given sets of n points there
    exists a labeling of each set such that the largest compatible matching has   O(n2/(ℓ+1))  edges.
    Finally, we show that   Θ(logn)  copies of any set of n points are necessary and
    sufficient for the existence of a labeling such that any compatible matching consists
    only of a single edge.'
