A note on generalized Jordan derivations of triangular rings

In this talk rst of all we reveiw some results concerning (generalized) Jordan derivationson triangular ring. Then under some conditions we shall prove that every generalized Jor-dan derivation associate with Hochschild ۲-cocycle a on a triangular ring is a generalizedderivation associate with Hochschild ۲-cocycle a .
