K3曲面的导出等价与交换等价

Derived and abelian equivalence of K3 surfaces

Daniel Huybrechts

摘要:

Tom Bridgeland构造了K3曲面的显式稳定性条件。本文试图对这些特殊的例子,特别是对潜在的t结构的心脏有更多的了解。本文证明了两个K3曲面X和X'是导出等价的当且仅当存在复极化B+iw和B'+ iw',使得相应的阿贝尔范畴A(B+iw)和A(B'+ iw ')是等价的.我们详细研究了A(B+iw)的极小对象,并在Fourier-Mukai变换下研究了其稳定性.

英文摘要:

Tom Bridgeland constructed explicit stability conditions on K3 surfaces. This paper attempts to shed more light on these particular examples, especially on the hearts of the underlying t-structures. We prove that two K3 surfaces X and X' are derived equivalent if and only if there exist complexified polarizations B+iw and B'+iw' such that the associated abelian categories A(B+iw) and A(B'+iw') are equivalent. We study in detail the minimal objects of A(B+iw) and investigate stability under Fourier-Mukai transform.
