On Jordan Triple α-*Centralizers Of Semiprime Rings

Demonstratio Mathematica, 2014
Let R be a 2-torsion free semiprime ring equipped with an involution *. An additive mapping T : R→R is called a left (resp. right) Jordan α-*centralizer associated with a function α: R→R if T(x2)=T(x)α(x*) (resp. T(x2)=α(x*)T(x)) holds for all x ∊ R.

Jordan derivations revisited

Mathematical Proceedings of the Cambridge Philosophical Society, 2005
Let d be a Jordan derivation from a ring A into an A-bimodule M. Our main result shows that the restriction of d to the ideal of A generated by certain higher commutators of A is a derivation. This general statement is used for proving that under various additional conditions d must be a derivation on A.

Ternary structures in Hilbert spaces

, 2011
PhDTernary structures in Hilbert spaces arose in the study of in nite dimensional manifolds in di erential geometry. In this thesis, we develop a structure theory of Hilbert ternary algebras and Jordan Hilbert triples which are Hilbert spaces equipped

Nonlinear Mixed Bi-Skew Jordan-Type Higher Derivations on ∗-Algebras

Mathematics
Let A be a unital ∗-algebra containing a nontrivial projection. In this paper, we show that every nonlinear mixed bi-skew Jordan-type higher derivation on A is an additive higher ∗-derivation.

Dam safety management methodology in front of the national dam safety policy [PDF]

REM: International Engineering Journal
Most of the dams registered on the National Information System on Dam Safety (SNISB of Brazil) do not have enough information to assess whether they fit into the National Dam Safety Policy (PNSB), or to assess their safety conditions.

Non-linear η-Jordan ∗-derivation maps on prime C∗-algebras

, 2017
Let A be a prime C ∗−algebra that contains a non-trivial projection and η be a non-zero complex number that | η |6= 1 and ψ be the η-Jordan ∗-derivation map on A, that is, for every A, B ∈ A, ψ(A η B) = ψ(A) η B + A η ψ(B) where A η B = AB + ηBA ...

ON CERTAIN IDENTITY RELATED TO JORDAN *-DERIVATIONS

Glasnik matematički, 2015
In this paper we prove the following result. Let H be a real or complex Hilbert space, let L(H) be the algebra of all bounded linear operators on H and let A(H) ⊆ L(H) be a standard operator algebra. Suppose we have an additive mapping D:A(H) → L(H) satisfying the relation D(An)=D(A)A* n-1+AD(An-2)A* +An-1D(A) for all A A(H) and some fixed integer n>1.

Jordan Triple Higher Derivations on Prime Rings

, 2015
In this paper, we develop some important results relating to the concepts of triple higher derivation and Jordan triple higher derivation on ring R. We show that under certain conditions on R, every Jordan triple higher derivation on R is triple higher ...

Study on Noncommutative Jordan Real Division Algebras of Dimension 8, Whose Lie Derivation Algebra Is Not Trivial

, 1995
In this paper we study the noncommutative Jordan real division algebras of dimension 8, whose Lie derivation algebra is nontrivial and give an affirmative answer to a question posed by Benkart and Osborn.
