p-adic域上波动型伪微分方程解的衰减性

Decay of solutions of wave-type pseudo-differential equations over p-adic fields

W. A. Zuniga-Galindo

摘要:

在80年代,提出了几种使用p-adic数的物理模型。特别是p-adic量子力学的各种模型。由于这一事实出现了几个新的数学问题,其中,研究p-adic伪微分方程。在本文中,我们开始研究p-adic领域的波型伪微分方程的解决方案的衰减,这些方程介绍了Kochubei在问题的特点的p-adic波函数使用伪微分算子。我们证明了p-adic波动型方程的解具有与经典广义波动方程的解相似的衰减性。

英文摘要:

During the eighties several physical models using p-adic numbers were proposed. Particularly various models of p-adic quantum mechanics. As a consequence of this fact several new mathematical problems emerged, among them, the study of p-adic pseudo-differential equations. In this paper we initiate the study of the decay of the solutions of wave-type pseudo-differential equations over p-adic fields; these equations were introduced by Kochubei in connection with the problem of characterizing the p-adic wave functions using pseudo-differential operators. We show that the solutions of p-adic wave-type equations have a decay similar to the solutions of classical generalized wave equations.
