Positive half-characters and the Laplace transformation

It is shown that the image of the conical semigroup S under the natural mapping of it to its second semigroup of positive semicharacters (Ŝ+)^+  is a total subset of the space of continuous functions on Ŝ+ approaching zero at infinity. This allows one to establish a number of properties...

Description
Summary:It is shown that the image of the conical semigroup S under the natural mapping of it to its second semigroup of positive semicharacters (Ŝ+)^+  is a total subset of the space of continuous functions on Ŝ+ approaching zero at infinity. This allows one to establish a number of properties of the semigroup Ŝ+ and of the Laplace transform of measures on it.
