Colorful four-point piercing conjecture for two families of circles
Let and be finite families of circles in . Suppose that for every and .
Colorful four-point piercing conjecture. Either or can be pierced by points.
This is proposed as a colorful analogue of Danzer's four-point piercing theorem for pairwise intersecting families of circles. The source presents it as a future-work conjecture and gives no resolution.
