    The maximum number of halving lines and the rectilinear crossing number of Kn for n
    Download  www.csun.edu
    For n 27 we present exact values for the maximum number h(n) of halving lines and h(n) of halving pseudolines, determined by n points in the plane. For this range of values of n ...
