摘要翻译:
在最近的预印本中,Y.Namikawa提出了一个关于幂零轨道的q-阶乘终止及其双分几何的猜想。他证明了他对经典单李代数的猜想。在这篇注记中,我们证明了他关于例外单李代数的猜想。对于双形几何,与经典情形相反,出现了两种新类型的Mukai Flop。

英文摘要:
In a recent preprint, Y. Namikawa proposed a conjecture on Q-factorial terminalizations and their birational geometry of nilpotent orbits. He proved his conjecture for classical simple Lie algebras. In this note, we prove his conjecture for exceptional simple Lie algebras. For the birational geometry, contrary to the classical case, two new types of Mukai flops appear.
