关于反Wick符号作为Gelfand-Shilov广义函数

On the anti-Wick symbol as a Gelfand-Shilov generalized function

Laurent Amour, Nicolas Lerner, Jean Nourrigat

摘要:

证明了将$ {\cal S}(\R^n)$映射到${\cal S}'(\R^n)$的算子的反Wick符号仍然可以定义为一个Gelfand-Shilov广义函数,该算子一般不是一个调和分布.这个结果依赖于涉及Schwartz和Gelfand-Shilov空间的检验函数空间嵌入。还给出了关于Schwartz和Gevrey空间的一个附加嵌入。

英文摘要:

The purpose of this article is to prove that the anti-Wick symbol of an operator mapping $ {\cal S}(\R^n)$ into ${\cal S}'(\R^n)$, which is generally not a tempered distribution, can still be defined as a Gelfand-Shilov generalized function. This result relies on test function spaces embeddings involving the Schwartz and Gelfand-Shilov spaces. An additional embedding concerning Schwartz and Gevrey spaces is also given.
