关于伪微分算子在Gevrey空间上的作用

On the action of pseudo-differential operators on Gevrey spaces

Baptiste Morisse

摘要:

本文研究了伪微分算子在Gevrey空间上的作用。我们介绍了类的经典符号的空间Gevrey正则性。由于符号$p(\cdot,ξ)$的空间Gevrey正则性可以取决于频率$ξ$,所以相关联的伪微分算子$op(p)$的动作可以引起正则性的损失。证明是基于一个para-product分解。

英文摘要:

In this paper we study the action of pseudo-differential operators acting on Gevrey spaces. We introduce classes of classical symbols with spatial Gevrey regularity. As the spatial Gevrey regularity of a symbol $p(\cdot,ξ)$ may depend on the frequency $ξ$, the action of the associated pseudo-differential operator $op(p)$ may induce a loss of regularity. The proof is based on a para-product decomposition.
