Generalized inflations and null extensions

open access: yes, 2004
An inflation of an algebra is formed by adding a set of new elements to each element in the original or base algebra, with the stipulation that in forming products each new element behaves exactly like the element in the base algebra to which it is ...

Mehler hemigroups and embedding of discrete skew convolution semigroups on simply connected nilpotent Lie groups [PDF]

open access: yes, 2008
It is shown how discrete skew convolution semigroups of probability measures on a simply connected nilpotent Lie group can be embedded into Lipschitz continuous semistable hemigroups by means of their generating functionals.

On completely simple semigroups

open access: yes, 2012
In this paper completely simple semigroups or generalized groups are considered. We characterize generalized groups which are normal generalized groups. Homomorphisms of generalized groups are considered.

Direct products of automatic semigroups

open access: yes, 2000
It is known that the direct product of two automatic groups is automatic. The notion of automaticity has been extended to semigroups, and this result for groups has been generalized to automatic monoids.

Bochner's Theorem and the Hausdorff Moment Theorem on foundation Topological Semigroups

open access: yes, 1985
One of the most basic theorems in harmonic analysis on locally compact commutative groups is Bochner's theorem (see [16, p. 19]). This theorem characterizes the positive definite functions. In 1971, R. Lindhal and P. H.
