代数向量丛模栈的上同调

Cohomology of the moduli stack of algebraic vector bundles

Toni Annala, Ryomei Iwasa

摘要:

设$\mathscr{V}\mathrm{ect}_n$是概图上秩为$n$的向量丛的模栈.证明了:若$E$是一个具有有限拟光滑转移且满足投射丛公式的Zapriki层,则对于任何方案$S$,$E^*(\mathscr{V}\mathrm{ect}_{n,S})$都是由$E^*(S)$上的陈类$c_1,\dotsc,c_n$自由生成的.例子包括所有乘法局部化不变量。

英文摘要:

Let $\mathscr{V}\mathrm{ect}_n$ be the moduli stack of vector bundles of rank $n$ on schemes. We prove that, if $E$ is a Zariski sheaf of ring spectra which is equipped with finite quasi-smooth transfers and satisfies the projective bundle formula, then $E^*(\mathscr{V}\mathrm{ect}_{n,S})$ is freely generated by Chern classes $c_1,\dotsc,c_n$ over $E^*(S)$ for any scheme $S$. Examples include all multiplicative localizing invariants.
