本文證明了如果莫里森錐體猜想對一個光滑卡拉比-丘 threefold Y 成立,那麼它對任何與 Y 形變等價的光滑卡拉比-丘 threefold 也成立。
The Morrison Cone Conjecture, concerning the geometry of nef and movable cones in Calabi-Yau threefolds, holds true for any smooth Calabi-Yau threefold that is deformation-equivalent to another threefold where the conjecture already holds.
