We prove that, for q odd, a set of q + 2 points in the projective plane over the field with q elements has at least 2q − c odd secants, where c is a constant and an odd secant is a line incident with an odd number of points of the set.

在奇割线很少的点集上

我们证明，对于q奇数，一组q+ 2 点在场上的投影平面上q元素至少有 2q-C奇数割线，其中C是一个常数，奇数割线是一条与集合中奇数个点入射的线。
