哈代测不准原理的动力学版本:综述

Dynamical versions of Hardy's uncertainty principle: A survey

Aingeru Fernández-Bertolin, Eugenia Malinnikova

摘要:

哈代不确定性原理说,没有函数比高斯函数更好地与其傅里叶变换一起局部化。教科书证明的结果,以及原来的证明之一,由哈代,是指Phragmén-Lindelöf定理。本文首先描述了Hardy不确定性与薛定谔方程之间的联系,并在此基础上利用Liouville定理给出了Hardy结果的一个新的证明.这个证明与哈代的第二个证明有关,这个证明已经被遗忘了。然后,我们综述了最近的结果动力学版本的哈代定理。

英文摘要:

The Hardy uncertainty principle says that no function is better localized together with its Fourier transform than the Gaussian. The textbook proof of the result, as well as one of the original proofs by Hardy, refers to the Phragmén-Lindelöf theorem. In this note we first describe the connection of the Hardy uncertainty to the Schrödinger equation, and give a new proof of Hardy's result which is based on this connection and the Liouville theorem. The proof is related to the second proof of Hardy, which has been underservedly forgotten. Then we survey the recent results on dynamical versions of Hardy's theorem.
