Berkovich曲线上p-adic微分方程的无穷小变形

Infinitesimal deformation of p-adic differential equations on Berkovich curves

Andrea Pulita

摘要:

证明了若拟光滑Berkovich曲线$X$上的微分方程$\mathscr{F}$关于$X$的自同构$σ$具有一定的相容性条件,且该自同构充分接近恒等式,则$\mathscr{F}$获得$σ$的半线性作用(即提升作用于$X$).推广了Yves André,Lucia Di Vizio和作者关于$p$ -adic $q$ -差分方程的工作.我们还得到了Morita的$p$ -adic Γ函数的应用,以及$p$ -adic $L$ -函数的相关值。

英文摘要:

We show that if a differential equations $\mathscr{F}$ over a quasi-smooth Berkovich curve $X$ has a certain compatibility condition with respect to an automorphism $σ$ of $X$, and if the automorphism is sufficiently close to the identity, then $\mathscr{F}$ acquires a semi-linear action of $σ$ (i.e. lifting that on $X$). This generalizes the previous works of Yves André, Lucia Di Vizio, and the author about $p$-adic $q$-difference equations. We also obtain an application to Morita's $p$-adic Gamma function, and to related values of $p$-adic $L$-functions.
