向井空翻和P-扭转

Mukai flops and P-twists

N. Addington, W. Donovan, C. Meachan

摘要:

与向井触发器X -> X'相关联的,一方面是一个等价序列D(X)-> D(X'),这是由Kawamata和Namikawa提出的,另一方面是D(X)的自等价序列,这是由Huybrechts和Thomas提出的。我们对两者之间的关系有了一个完整的了解。我们对标准的触发器做同样的事情,将Bondal和Orlov导出的等价物与球面扭曲联系起来,将Atiyah触发器的一个著名故事扩展到更高的维度。

英文摘要:

Associated to a Mukai flop X ---> X' is on the one hand a sequence of equivalences D(X) -> D(X'), due to Kawamata and Namikawa, and on the other hand a sequence of autoequivalences of D(X), due to Huybrechts and Thomas. We work out a complete picture of the relationship between the two. We do the same for standard flops, relating Bondal and Orlov's derived equivalences to spherical twists, extending a well-known story for the Atiyah flop to higher dimensions.
