Quasi-Mixing C0-Semigroups and Their Relations With Recurrent C0-Semigroups

open access: yesمجلة بغداد للعلوم
This article presents and investigates the concept of the quasi-mixing C0-semigroups. It is proved that the quasi-mixing of an invertible C0-semigroup is equivalent to the quasi-mixing of its inverse.

On The Amenability Of Inverse Semigroup Actions

open access: yes
The search for an appropriate notion of amenability for inverse semigroups is an ongoing program in operator algebras. This thesis approaches this problem using inverse semigroup actions.

The Semigroup and the Inverse of the Laplacian on the Heisenberg Group

open access: yesCubo, 2010
By decomposing the Laplacian on the Heisenberg group into a family of parametrized partial differential operators Lt ,t ∈ R {0}, and using parametrized Fourier-Wigner transforms, we give formulas and estimates for the strongly continuous one ...

An Invitation to Combinatorial Inverse Semigroup Theory [PDF]

open access: yes
Combinatorial inverse semigroup theory is the study of free inverse monoids, their closed inverse submonoids, and their homomorphic images, given in terms of presentations of inverse monoids by generators and relations.
