This family is characterized by the property that each cubic fourfold X in the family has an involution such that the induced involution on the Fano variety F of lines in X is symplectic and has a K3 surface S in the fixed locus. The main result establishes a relation between X and S on the level of Chow motives. As a consequence, we can prove finite-dimensionality of the motive of certain members of the family.

More precisely, we obtain the Betti numbers of Kirwan’s resolution of the moduli space. Furthermore, by applying decomposition theorem we obtain the Betti numbers of the intersection cohomology of Baily-Borel compactification of the moduli space.展开更多

This paper attempts to make a tentative probe into the translator's subjectivity manifested in the translation of Fu Sheng Liu Ji by Shen Fu on the basis of George Steiner's fourfold translation motion theory, namely"trust", "aggression","incorporation"and"compensation". By the study, we may obtain scientific understanding of how the translation is shaped by the translator's subjectivity, thus affirming the importance and necessity of the later in literary translation.展开更多

文摘This note is about the Chow groups of a certain family of smooth cubic fourfolds. This family is characterized by the property that each cubic fourfold X in the family has an involution such that the induced involution on the Fano variety F of lines in X is symplectic and has a K3 surface S in the fixed locus. The main result establishes a relation between X and S on the level of Chow motives. As a consequence, we can prove finite-dimensionality of the motive of certain members of the family.
