我们在 B 型拓扑弦理论中构造 D 膜范畴作为弦场运动方程的解。使用超连接的形式主义,我们证明这些解决方案形成了 Bondal 和 Kapranov 结构的变体。本分析是对 Lazaroiu 最近工作的阐述。我们还评论了弦场理论与道格拉斯、阿斯平沃尔和劳伦斯的派生范畴方法之间的关系。非全纯变形在该结构中出现了一些意想不到的效果。
We construct D-brane categories in B-type topological string theory as solutions to string field equations of motion. Using the formalism of superconnections, we show that these solutions form a variant of a construction of Bondal and Kapranov. This analysis is an elaboration on recent work of Lazaroiu. We also comment on the relation between string field theory and the derived category approach of Douglas, and Aspinwall and Lawrence. Non-holomorphic deformations make a somewhat unexpected appearance in this construction.
