抽象Cauchy问题卷积解的锐延拓

Sharp extensions for convoluted solutions of abstract Cauchy problems

Valentin Keyantuo, Pedro J. Miana, Luis Sánchez-Lajusticia

摘要:

本文给出了巴拿赫空间中抽象柯西问题卷积解的一个强推广结果。主要的技术是使用这些解决方案的代数结构(通常的卷积产品$\ast$),由Duhamel公式的一个版本定义。我们从一类新的测试函数定义代数同态,并将我们的结果应用到具体的运营商。最后,我们引入了$k$ -分布半群的概念,推广了分布半群的概念。

英文摘要:

In this paper we give sharp extension results for convoluted solutions of abstract Cauchy problems in Banach spaces. The main technique is the use of algebraic structure (for usual convolution product $\ast$) of these solutions which are defined by a version of the Duhamel formula. We define algebra homomorphisms from a new class of test-functions and apply our results to concrete operators. Finally, we introduce the notion of $k$-distribution semigroups to extend previous concepts of distribution semigroups.
