设X$是光滑流形,$mathbf{k}$是交换(或至少$mathbb{E}_2$)环谱.给定一个光滑的精确拉格朗日量$Lhookrightarrow T^*X$,微局部层理论(遵循Kashiwara-Schapira)自然地在$L$上指定一个局部常数范畴层,其纤维等价于$mathbf{k}$-谱范畴$mathrm{Mod}(mathbf{k})$。我们证明了局部范畴系统的分类映射是通过稳定的高斯映射$L 八箭头U/O$与J$-同态U/O $的去环 {Pic}(mathbf{S})$.作为应用,结合Guillermou [Gui]的结果,我们恢复了Abouzaid-Kragh [AbKr]关于合成$L平凡性的一个结果 八箭头U/O 当$L$是加法紧的时,有八箭头Bmathrm{Pic}(mathbf{S})$.
Let $X$ be a smooth manifold and $mathbf{k}$ be a commutative (or at least $mathbb{E}_2$) ring spectrum. Given a smooth exact Lagrangian $Lhookrightarrow T^*X$, the microlocal sheaf theory (following Kashiwara--Schapira) naturally assigns a locally constant sheaf of categories on $L$ with fiber equivalent to the category of $mathbf{k}$-spectra $mathrm{Mod}(mathbf{k})$. We show that the classifying map for the local system of categories factors through the stable Gauss map $L ightarrow U/O$ and the delooping of the $J$-homomorphism $U/O ightarrow Bmathrm{Pic}(mathbf{S})$. As an application, combining with previous results of Guillermou [Gui], we recover a result of Abouzaid--Kragh [AbKr] on the triviality of the composition $L ightarrow U/O ightarrow Bmathrm{Pic}(mathbf{S})$, when $L$ is in addition compact.
