扭曲$L_\infty$ -态射的同伦类

The Homotopy Class of twisted $L_\infty$-morphisms

Andreas Kraft, Jonas Schnitzer

摘要:

Dolgushev的整体形式依赖于无挠共变导数的选择。我们证明了关于两个不同的共变导数的全球化形式是同伦的。更明确地说,我们得出的声明,证明了一个更一般的同伦等价的$L_\infty$ -态射扭曲规范等效的Maurer-Cartan元素之间。

英文摘要:

The global formality of Dolgushev depends on the choice of a torsion-free covariant derivative. We prove that the globalized formalities with respect to two different covariant derivatives are homotopic. More explicitly, we derive the statement by proving a more general homotopy equivalence between $L_\infty$-morphisms that are twisted with gauge equivalent Maurer-Cartan elements.
