摘要:

我们介绍和研究了一些新的空间的超可微函数和超分布,我们将我们的结果的卷积的超分布的研究。利用检验函数空间$\mathcal{O}^{\ast}_{C}(\mathbb{R}^{d})$的对偶性,分析了调和超分布的卷积子空间$\mathcal{O}'^{\ast}_{C}(\mathbb{R}^{d})$.我们还研究了超分布空间与平移不变巴拿赫空间的回火超分布,并利用它们的性质提供了一个完整的表征一般卷积Roumieu超分布通过空间的可积超分布。证明了两个Roumieu超分布$T,S\in \DD'^{\{M_p\}}\left(\RR^d\right)$的卷积存在的充要条件是对每个$φ\in\DD^{\{M_p\}}\left(\RR^d\right)$都有$\left(φ*\check{S}\right)T\in\DD'^{\{M_p\}}_{L^1}\left(\RR^d\right)$.

英文摘要:

We introduce and study a number of new spaces of ultradifferentiable functions and ultradistributions and we apply our results to the study of the convolution of ultradistributions. The spaces of convolutors $\mathcal{O}'^{\ast}_{C}(\mathbb{R}^{d})$ for tempered ultradistributions are analyzed via the duality with respect to the test function spaces $\mathcal{O}^{\ast}_{C}(\mathbb{R}^{d})$, introduced in this article. We also study ultradistribution spaces associated to translation-invariant Banach spaces of tempered ultradistributions and use their properties to provide a full characterization of the general convolution of Roumieu ultradistributions via the space of integrable ultradistributions. We show that the convolution of two Roumieu ultradistributions $T,S\in \DD'^{\{M_p\}}\left(\RR^d\right)$ exists if and only if $\left(φ*\check{S}\right)T\in\DD'^{\{M_p\}}_{L^1}\left(\RR^d\right)$ for every $φ\in\DD^{\{M_p\}}\left(\RR^d\right)$.
