摘要翻译:
我们研究了不可约全纯辛变体的双分几何,它是由包含一个三次涡卷的一般三次四折叠的线变体所产生的。我们计算了充足锥和运动锥,并给出了一个无限阶的双形自同构来解释运动锥的室分解。

英文摘要:
We study the birational geometry of irreducible holomorphic symplectic varieties arising as varieties of lines of general cubic fourfolds containing a cubic scroll. We compute the ample and moving cones, and exhibit a birational automorphism of infinite order explaining the chamber decomposition of the moving cone.
