Abstract

Let T{\mathcal{T}} be a triangular algebra. We say that D={Dn:nN}L(T)D=\{D_{n}: n\in N\}\subseteq L({\mathcal{T}}) is a Jordan higher derivable mapping at GG if Dn(ST+TS)=i+j=n(Di(S)Dj(T)+Di(T)Dj(S))D_{n}(ST+TS)=\sum_{i+j=n}(D_{i}(S)D_{j}(T)+D_{i}(T)D_{j}(S)) for any S,TTS,T\in {\mathcal{T}} with ST=GST=G. An element GTG\in {\mathcal{T}} is called a Jordan higher all-derivable point of T{\mathcal{T}} if every Jordan higher derivable linear mapping D={Dn}nND=\{D_{n}\}_{n\in N} at GG is a higher derivation. In this paper, under some mild conditions on T{\mathcal{T}}, we prove that some elements of T{\mathcal{T}} are Jordan higher all-derivable points. This extends some results in [6] to the case of Jordan higher derivations.
