在较早的文件的概念,一个过滤导出等价介绍,它表明,如果两个K3曲面承认这样的等价,那么他们是同构的。在本文中,我们研究更精细方面的过滤导出等价有关的行动上的上同调实现的Mukai动机。它表明,如果一个过滤导出的等价K3曲面之间也保持足够的锥,那么可以找到一个同构,诱导相同的映射上同调实现的等价。
In an earlier paper the notion of a filtered derived equivalence was introduced, and it was shown that if two K3 surfaces admit such an equivalence, then they are isomorphic. In this paper we study more refined aspects of filtered derived equivalences related to the action on the cohomological realizations of the Mukai motive. It is shown that if a filtered derived equivalence between K3 surfaces also preserves ample cones then one can find an isomorphism that induces the same map as the equivalence on the cohomological realizations.
