摘要翻译:
本文研究了光滑射影簇X上局部无丛E的全空间零截面上支撑的丛,当E的顶外幂与X的正则丛同构时,我们用a-无穷代数语言重新表述了这个构造,并给出了E是正则丛的简单刻画。

英文摘要:
We investigate sheaves supported on the zero section of the total space of a locally-free sheaf E on a smooth, projective variety X when the top exterior power of E is isomorphic to the canonical bundle of X. We rephrase this construction using the language of A-infinity algebra and provide a simple characterisation of the case E is simply the canonical bundle itself.
