Anti-derivations on triangular rings

[摘要] ‎The aim of this paper is to give necessary and sufficient conditions for anti-derivations to be zero on 2-torsion free triangular rings. As application of our main result‎, ‎we present sufficient conditions for anti-derivations to be zero on block upper triangular matrix rings‎.
