Abstract:
In this paper, we prove that every orthogonally higher ring derivation is a higher ring derivation. Also we find the general solution of the pexider orthogonally higher ring derivations\begin{align*}\left\{\begin{array}{lr}f_n(x+y)=g_n(x)+h_n(y), \;\left\langle x,y \right\rangle =۰,\\f_n(xy) = \sum_{i+j=n} g_i(x)h_j(y).\end{array}\right.\end{align*}Then we prove that for any approximate pexider orthogonally higher ring derivation under some control functions \varphi(x,y) and \psi(x,y) , there exists a unique higher ring derivation D=\{d_n\}_{n=۰}^\infty , near \{f_n\}_{n=۰}^\infty , \{g_n\}_{n=۰}^\infty and \{h_n\}_{n=۰}^\infty estimated by \varphi and \psi .
