k-fan 是平面上的一个点和从该点发出的 k 条半线。受 A. Kaneko 和 M. Kano 提出的一个巧妙问题的启发,我们研究了平面上两个或多个概率度量的 k-fans 的均分,以及其他规定比率的划分。我们的结果之一:对于任意两个测度,都有一个 4 扇形,其中一个扇区包含这两个测度的 2 5 个,而其余三个扇区中的每一个包含这两个测度的 1 5 个。
A k-fan is a point in the plane and k semilines emanating from it. Motivated by a neat question of A. Kaneko and M. Kano, we study equipartitions by k-fans of two or more probability measures in the plane, as well as partitions in other prescribed ratios. One of our results: for any two measures there is a 4-fan such that one of its sectors contains 2 5 of both measures, and each of the the remaining three sectors contains 1 5 of both measures.
