作为数列空间代数的广义函数代数

Generalized function algebras as sequence space algebras

Antoine Delcroix, Maximilian F. Hasler, Stevan Pilipović, Vincent Valmorin

摘要:

给出了基本局部凸代数上各种广义函数代数的拓扑描述。该框架由代数的序列与适当的超(伪)度量定义的序列的指数权重。这样一个嵌入狄拉克δ分布的代数在基本空间上诱导出离散拓扑。这个结果与Schwartz关于分布相乘的不可能性结果类似。

英文摘要:

A topological description of various generalized function algebras over corresponding basic locally convex algebras is given. The framework consists of algebras of sequences with appropriate ultra(pseudo)metrics defined by sequences of exponential weights. Such an algebra with embedded Dirac's delta distribution induces discrete topology on the basic space. This result is in analogy to Schwartz' impossibility result concerning multiplication of distributions.
