On the Laplace transform on semilattices
摘要
The definition of the Laplace transform of a bounded Radon measure on an Abelian topological semigroup is due to N. Bourbaki. In this note, we generalise this definition and prove inverse formulas for the Laplace transform of measures on semilattices of open-and-compact sets in both discrete and non-discrete cases. These are partial answers to a question posed by Yu. I. Lyubich.
