- Let T be a unital triangular algebra, let n > 1 be an integer, let gamma be an invertible element of Z(T), the center of T, and let Psi, Omega:\mathcal{T}\rightarrow \mathcal{T}$ be additive mappings satisfying \begin{align*} Ψ(X^n) = γX^{n - 1}Ω(X) = γΩ(X) X^{n - 1}\end{align*} for all $X \in \mathcal{T}$. If $Ω(\textbf{1}) \in Z(\mathcal{T})$, then $Ψ$ and $Ω$ are two-sided centralizers on $\mathcal{T}$ and also $Ψ= γΩ$. Moreover, using a functional identity, a characterization of two-sided generalized derivations is presented. Some other related results are also discussed.
