Monogenic free inverse semigroups and partial automorphisms of regular rooted trees

open access: yesМатематичні Студії
For a one-to-one partial mapping on an infinite set, we present a criterion in terms of its cycle-chain decomposition that the inverse subsemigroup generated by this mapping is monogenic free inverse. We also give a sufficient condition for a regular

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.

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 ...
