一个非阿基米德的Wave Equation

A Non-Archimedean Wave Equation

Anatoly N. Kochubei

摘要:

设K是具有归一化绝对值$|\cdot |$的非阿基米德局部域。本文证明了一个“平面波”$f(t+ω_1 x_1+... +ω_nx_n)$,其中f是K上的Bruhat-Schwartz复值检验函数,$(t,x_1,..., x_n)\in K^{n+1}$,$\max\limits_{1\le j\le n}|ω_j|=1$,对任意f,满足一个齐次伪微分方程,它是经典波动方程的一个模拟.发展了该方程的柯西问题的理论。

英文摘要:

Let K be a non-Archimedean local field with the normalized absolute value $|\cdot |$. It is shown that a ``plane wave'' $f(t+ω_1 x_1+... +ω_nx_n)$, where f is a Bruhat-Schwartz complex-valued test function on K, $(t,x_1,..., x_n)\in K^{n+1}$, $\max\limits_{1\le j\le n}|ω_j|=1$, satisfies, for any f, a certain homogeneous pseudo-differential equation, an analog of the classical wave equation. A theory of the Cauchy problem for this equation is developed.
