ABSTRACT

In this work, we first establish a local Carleman estimate for the ultrahyperbolic Schrödinger equation which arises in some theories of modern physics such as quantum mechanics and string theory. Next, we prove a Hölder stability estimate for the Cauchy Problem. In the proof, we introduce a suitable cut-off function and extend Cauchy data in a Sobolev space to reduce the problem to another problem for functions with compact supports and then we apply the Carleman estimate.

超双曲薛定谔方程的柯西问题的条件稳定性

摘要

在这项工作中,我们首先建立了超双曲薛定谔方程的局部卡尔曼估计,该方程出现在现代物理学的一些理论中,如量子力学和弦论。接下来,我们证明柯西问题的 Hölder 稳定性估计。在证明中,我们引入了一个合适的截止函数并在 Sobolev 空间中扩展柯西数据,以将问题简化为具有紧支撑的函数的另一个问题,然后我们应用 Carleman 估计。
