Surjective isometries of C*-algebras: complex spectrum and periodicity

Concrete Operators
In this paper, we are interested in studying surjective isometries of C*-algebras with an emphasis on their complex spectrum. We do not require the isometries to be linear nor the C*-algebras to be unital.

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.

Pseudospectra in Banach Jordan Algebras

Mathematics
The primary focus of this paper is to extend the concept of pseudospectrum from operators and matrices to elements of a unital complex Banach Jordan algebra, thereby moving from the associative to the non-associative setting. We introduce the notion of ε-

On Mappings That Preserve the Jordan Product: A Revisited Study

Mathematics
We study bijective maps between algebras that preserve Jordan-type products. More precisely, given algebras A and B, we consider maps Θ:A→B satisfying Θ(AB+BA)=Θ(A)Θ(B)+Θ(B)Θ(A) or, more generally, preserving the Jordan triple product Θ({A,B,C})={Θ(A),Θ ...

On strongly Jordan zero-product preserving maps [PDF]

Sahand Communications in Mathematical Analysis, 2016
In this paper, we give a characterization of strongly Jordan zero-product preserving maps on normed algebras as a generalization of  Jordan zero-product preserving maps.
