This paper generalizes the formula sum from n=n to (I<sub>ns</sub>(v)I<sub>ns'</sub>(v)=δ<sub>ss'</sub>) to the case with two different v. I<sub>ns</sub>(v) is the rad
The general expression of vacuum polarization energymomentum tensors for scalar field is derived in one loop approximation. Some special cases are discussed. Pa
