Continuity of Gevrey-Hörmander pseudo-differential operators on modulation spaces
摘要:
设$s\ge 1$,$ω,ω_0\in \mathscr P_{E,s}^0$,$a\in Γ_{s}^{(ω_0)}$,并设$\mathscr B$是合适的不变拟Banach函数空间,证明了伪微分算子$\operatorname{Op} (a)$从$M(ω_0ω,\mathscr B )$到$M(ω,\mathscr B )$是连续的.
英文摘要:
Let $s\ge 1$, $ω,ω_0\in \mathscr P_{E,s}^0$, $a\in Γ_{s}^{(ω_0)}$, and let $\mathscr B$ be a suitable invariant quasi-Banach function space, Then we prove that the pseudo-differential operator $\operatorname{Op} (a)$ is continuous from $M(ω_0ω,\mathscr B )$ to $M(ω,\mathscr B )$.
