Constrained Equitable 3-Cuttings

We investigate equitable 3-cuttings of two mass distributions in the plane (partitions of the plane into 3 sectors with a common apex such that each sector contains 1/3 of each mass). We prove the existence of a continuum of equitable 3-cuttings that satisfy some closure property. This permits us to generalize earlier results on both convex and non-convex equitable 3-cuttings with additional constraints.
