摘要:

我们考虑Fourier Lebesgue空间中不同类型的(局部)积$f_1 f_2$.此外,我们证明了存在这样的产品满足适当的波前性质的其他分布。我们还考虑了具有适当多项式$P $和$G$的形式为$$ \qquad P(x,D)f = G(x,J_k f), $$的半线性方程.若解局部属于适当的加权Fourier Lebesgue空间${\mathscr F}L^q_{(ω)} (\rr d)$,且$P$在$(x_0,ξ_0),$上是非特征的,则证明了$(x_0,ξ_0)\not \in WF_{{\mathscr F}L^q_{(\widetilde ω)}} (f)$,其中$\widetildeω$依赖于$ω$,$P$和$G$ .

英文摘要:

We consider different types of (local) products $f_1 f_2$ in Fourier Lebesgue spaces. Furthermore, we prove the existence of such products for other distributions satisfying appropriate wave-front properties. We also consider semi-linear equations of the form $$ \qquad P(x,D)f = G(x,J_k f), $$ with appropriate polynomials $P $ and $G$. If the solution locally belongs to appropriate weighted Fourier Lebesgue space ${\mathscr F}L^q_{(ω)} (\rr d)$ and $P$ is non-characteristic at $(x_0,ξ_0),$ then we prove that $(x_0,ξ_0)\not \in WF_{{\mathscr F}L^q_{(\widetilde ω)}} (f)$, where $\widetildeω$ depends on $ω$, $P$ and $G$.
