摘要
We prove that if we are given a set of points P and set of lines L in F-q(2) such that vertical bar P parallel to|L vertical bar >= q(8/3), then the set of distinct distances between points from P and lines from L contains a positive proportion of all distances. Using the same techniques, we also obtain a generalization of this result in higher dimensional cases.
