Abstract

Let A and B be C*-algebras, and let ? be a derivation on the tensor product A ? B endowed with a uniform cross norm. In this paper, we present a decomposition for ? as ? = ? ? id + id ? ?, where id stands for the identity operator and ? and ? are derivations on A and B, respectively. Moreover, the concept of flow on the tensor product of C*-algebras and some properties of tensor sum are investigated.
