基于Chern-Weil的矩阵分解的Chern character
Chern character for matrix factorizations via Chern-Weil
摘要:
给定一个矩阵分解,我们使用Atiyah类给它的Chern特征标一个代数Chern-Weil型构造;这使我们能够以显式的方式实现Chern特征标。将已有结果推广到任何光滑$k$ -代数$Q$($k$是含$\mathbb{Q}$的交换环)和任何$f\in Q$,这与Platt最近的一个结果一致.我们还研究了陈特征标的一些基本性质。
英文摘要:
Given a matrix factorization, we use the Atiyah class to give an algebraic Chern-Weil type construction to its Chern character; this allows us to realize the Chern character in an explicit way. It also generalizes the existing result to any smooth $k$-algebra $Q$ ($k$ a commutative ring containing $\mathbb{Q}$) and any $f\in Q$, which agrees with a recent result of Platt. We also study some basic properties of the Chern character.
