Let $\mathscr{H}$ be an infinite-dimensional complex Hilbert space and $𝔄$ be a standard operator algebra on $\mathscr{H}$ which is closed under the adjoint operation. It is shown that every nonlinear $*$-Lie higher derivation $𝒟={\left\{{\delta }_n\right\}}_{n\in \mathbb{N}}$ of $𝔄$ is automatically an additive higher derivation on $𝔄$. Moreover, $𝒟={\left\{{\delta }_n\right\}}_{n\in \mathbb{N}}$ is an inner $*$-higher derivation.

Let $R$ be a prime ring, with no non-zero nil right ideal, $d$ a non-zero drivation of $R$, $I$ a non-zero two-sided ideal of $R$. If, for any $x$, $y\in I$, there exists $n=n\left(x,y\right)\ge 1$ such that ${\left(d\left(\left[x,y\right]\right)-\left[x,y\right]\right)}^n=0$, then $R$ is commutative. As a consequence we extend the result to Lie ideals.

Under some conditions we prove that every generalized Jordan triple derivation on a Lie triple system is a generalized derivation. Specially, we conclude that every Jordan triple $\theta$-derivation on a Lie triple system is a $\theta$-derivation.

Let $R$ be a $2$-torsion free $*$-prime ring, $d$ a derivation which commutes with $*$ and $J$ a $*$-Jordan ideal and a subring of $R$. In this paper, it is shown that if either $d$ acts as a homomorphism or as an anti-homomorphism on $J$, then $d=0$ or $J\subseteq Z\left(R\right)$. Furthermore, an example is given to demonstrate that the $*$-primeness hypothesis is not superfluous.

Let $R$ be a $2$-torsion free prime ring. Suppose that $\theta ,\phi$ are automorphisms of $R$. In the present paper it is established that if $R$ admits a nonzero Jordan left $(\theta ,\theta )$-derivation, then $R$ is commutative. Further, as an application of this resul it is shown that every Jordan left $(\theta ,\theta )$-derivation on $R$ is a left $(\theta ,\theta )$-derivation on $R$. Finally, in case of an arbitrary prime ring it is proved that if $R$ admits a left $(\theta ,\phi )$-derivation which acts also as a homomorphism (resp. anti-homomorphism) on a nonzero ideal of $R$, then $d=0$...

Let $R$ be a 2-torsion free prime ring and let $U$ be a Lie ideal of $R$ such that $u^2\in U$ for all $u\in U$. In the present paper it is shown that if $d$ is an additive mappings of $R$ into itself satisfying $d\left(u^2\right)=2ud\left(u\right)$ for all $u\in U$, then $d\left(uv\right)=ud\left(v\right)+vd\left(u\right)$ for all $u,v\in U$.
