China.201409080$ is a real number. It is shown that if $Phi:mathcal{A} tomathcal{B}$ is an additive map preserving $|cdot|^k$ for all normal elements; that is, $Phi(|A|^k)=|Phi(A)|^k $ for all normal elements $Ainmathcal A$, $Phi(I)$ is a projection, and there exists a positive number $c$ such that $Phi(iI)Phi(iI)^{*}leq
cPhi(I)Phi(I)^{*}$, then $Phi$ is the sum of a linear Jordan *-homomorphism and a conjugate-linear Jordan *-homomorphism. If, moreover, the map $Phi$ commutes with $|.|^k$ on $mathcal{A}$, then $Phi$ is the sum of a linear *-homomorphism and a conjugate-linear *-homomorphism. In the case when $k not=1$, the assumption $Phi(I)$ being a projection can be deleted.]]>http://bims.iranjournals.ir/article_724_15cc6b48cc93f3f328eb35b3ec30359a.pdfIranian Mathematical Society (IMS)Bulletin of the Iranian Mathematical Society1017-060X41Issue 7 (Special Issue)20151201A Haar wavelets approach to Stirling's formula99106725ENM.
