二射影空间合同点场与线把

The field of congruent points and line bundle between two progective space

同素对应二射影空间满足一定的条件时,存在两对对应合同点场,两对对应合同线把。且合同点场、线把具有特殊的位置关系。利用这一点,我们可以使二射影空间场移动成透射。

When two progective space satisfy certain condition, there exist two field of congruent points and line bundle. And it possess a special position relation. By which means, the two progective space may be transferred to progection.
