Extension techniques in C-cross products by compact group duals and quantum field theory

open access: yesElectronic Journal of Differential Equations, 2000
Using the methods developed in a previous paper, we consider the problem of extending endomorphisms to cross-product by compact group duals. Then we discuss some other applications to quantum field theory, mainly in connection with PCT symmetries.

Hom-Jordan and Hom-alternative bimodules

open access: yesExtracta Mathematicae, 2020
In this paper, Hom-Jordan and Hom-alternative bimodules are introduced. It is shown that Jordan and alternative bimodules are twisted via endomorphisms into Hom-Jordan and Hom-alternative bimodules respectively.

Clifford Semigroups and Seminear-Rings of Endomorphisms

open access: yes, 2017
In this project we consider the structure of semi groups of self mapping of a semi group S under pointwise composition, generated by the endomorphisms of S.

Endomorphisms of Linear Block Codes [PDF]

open access: yes
The automorphism groups of various linear codes are extensively studied yielding insights into the respective code structure. This knowledge is used in, e.g., theoretical analysis and in improving decoding performance, motivating the analyses of ...

Semigroup presentations [PDF]

open access: yes, 2012
In this thesis we consider in detail the following two fundamental problems for semigroup presentations: 1. Given a semigroup find a presentation defining it. 2. Given a presentation describe the semigroup defined by it.

Endomorphisms of profinite groups

open access: yesGroups, Geometry, and Dynamics, 2014
We obtain some general restrictions on the continuous endomorphisms of a profinite group G under the assumption that G has only finitely many open subgroups of each index (an assumption which automatically holds, for instance, if

Endomorphisms of the Riordan group

open access: yes, 2019
We state a characterization of endomorphisms of the Riordan group by means of suitable maps, acting on power series, that we name the coordinates of the endomorphism.
