Combining theorems of Voisin and Marian, Shen, Yin and Zhao, we compute the dimensions of the orbits under rational equivalence in the Mukai system of rank two and genus two. We produce several examples of algebraically coisotropic and constant cycle subvarieties.

Mukai 系统中的恒定循环和共各向同性子变体

结合Voisin和Marian、Shen、Yin和Zhao的定理，我们计算了二阶和二类Mukai系统有理等价下的轨道维数。我们产生了几个代数各向同性和恒定周期子变体的例子。
