Jordan centralizer maps on trivial extension algebras

open access: yesDemonstratio Mathematica, 2020
The structure of Jordan centralizer maps is investigated on trivial extension algebras. One may obtain some conditions under which a Jordan centralizer map on a trivial extension algebra is a centralizer map. As an application, we characterize the Jordan

Design and In Vitro Validation of an Orthopaedic Drill Guide for Femoral Stem Revision in Total Hip Arthroplasty [PDF]

open access: yesIEEE Journal of Translational Engineering in Health and Medicine
Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is ...

Numerical analysis on the centralization effect of improved horizontal well casing centralizer

open access: yesFrontiers in Energy Research, 2023
Horizontal well technology is a promising method for oil and gas development. During cementing operations in horizontal wells, it was found that conventional casing centralizers could not meet the requirements for casing cementing in expanded wellbores ...

McKay Centralizer Algebras [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
For a finite subgroup G of the special unitary group SU2, we study the centralizer algebra Zk(G) = EndG(V⊗k) of G acting on the k-fold tensor product of its defining representation V = C2.

Quasi Centralizers and Inner Derivations in a Closed Ideal of a Complex Banach Algebra [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2004
In this paper we show that, for an ideal J of a unital complex Banach algebra A, we have (i) under certain conditions the ? -quasi centralizer, the quasi centralizer, and the centralizer of J are all identical, and so they are subsets of the ?

On right (left) θ-centralizers on Banach algebras [PDF]

open access: yesJournal of Hyperstructures, 2023
Let A be a Banach algebra with unity 1, and θ : A → A be an continuous automorphism. In this paper we characterizea continuous linear map T : A → A which satisfies one of the following conditions:a, b ∈ A, ab = w =⇒ θ(a)T(b) = T(w),a, b ∈ A, ab = w =⇒ T ...

The structure of groups with cyclic commutator subgroups indecomposable to a subdirect product of groups [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The article studies finite groups indecomposable to subdirect product of groups (subdirectly irreducible groups), commutator subgroups of which are cyclic subgroups.

Commuting Conjugacy Class Graph of G when G / Z(G)~=D2n [PDF]

open access: yesMathematics Interdisciplinary Research, 2020
Suppose G is a finite non-abelian group and Γ(G) is a simple graph with the non-central conjugacy classes of G as its vertex set. Two different noncentral conjugacy classes C and B are assumed to be adjacent in Γ(G) if and only if there are elements a ...

Central neurocytoma

open access: yesJournal of Clinical Neuroscience, 2012
Central neurocytomas (CN) are rare intraventricular tumors with prominent neuronal differentiation. CN commonly arise in the lateral ventricles of young adults who predominantly present with raised intracranial pressure. Few studies have described the clinical, pathological, and radiological features of these tumors, and those that have are typically ...

A note on Jordan left *-centralizers on prime and semiprime rings with involution

open access: yesJournal of Taibah University for Science, 2017
The aim of this note is to give alternative and short proofs for some results to Ali et al. in [3] by using the relationship between the concepts of Jordan left *-centralizer and right centralizer on a 2-torsion free semiprime rings endowed with ...
