设$\mathcal M$是仿射线上的完整代数$\mathcal D$-模,处处正则,包括在无穷远处。Malgrange给出了一个完整的描述傅里叶-拉普拉斯变换$\widehat{\mathcal M}$,包括其斯托克斯乘数在无穷远,在条款的$\mathcal M$。设$F$是$\mathcal M$的全纯解的逆层。通过不规则Riemann-Hilbert对应,$\widehat{\mathcal M}$由$F$的增强Fourier-Sato变换$F^\curlywedge$确定。我们的目标是恢复Malgrange的结果在一个纯粹的拓扑方式,通过计算$F^\curlywedge$使用Borel-Moore循环。在本文中,我们还考虑了一些不规则的$\mathcal M$的,如在艾里方程的情况下,我们的周期是相关的最速下降路径。
Let $\mathcal M$ be a holonomic algebraic $\mathcal D$-module on the affine line, regular everywhere including at infinity. Malgrange gave a complete description of the Fourier-Laplace transform $\widehat{\mathcal M}$, including its Stokes multipliers at infinity, in terms of the quiver of $\mathcal M$. Let $F$ be the perverse sheaf of holomorphic solutions to $\mathcal M$. By the irregular Riemann-Hilbert correspondence, $\widehat{\mathcal M}$ is determined by the enhanced Fourier-Sato transform $F^\curlywedge$ of $F$. Our aim here is to recover Malgrange's result in a purely topological way, by computing $F^\curlywedge$ using Borel-Moore cycles. In this paper, we also consider some irregular $\mathcal M$'s, like in the case of the Airy equation, where our cycles are related to steepest descent paths.
