چکیده
|
Let $mathcal{a}$ and $mathcal{b}$ are $c^{{ast}} $-algebras. a linear map $phi:mathcal{arightarrow b}$ is $c^{ast}$-jordan homomorphism if it is a jordan homomorphism which preserves the adjoint operation. in this note we show that $c^{ast}$-jordan homomorphisms -under mild assumptions- preserving covariance set and covariance coset in $c^{ast}$-algebras.
