论文摘要
众所周知，每个Fano-Mukai属10的四倍X属属属于一个互动$τ$，该$τ$来自简单的代数类型$ {\ rm g} _2 $的weyl oft的中心。此事是唯一的定义为组合（x）中的共轭。在本说明中，我们描述了$τ$的固定点集，表面滚动扫除了$τ$ - invariant Lines。
It is known that every Fano-Mukai fourfold X of genus 10 is acted upon by an involution $τ$ which comes from the center of the Weyl group of the simple algebraic group of type ${\rm G}_2$. This involution is uniquely defined up to conjugation in the group Aut(X). In this note we describe the set of fixed points of $τ$ and the surface scroll swept out by the $τ$-invariant lines.
