Abstract
Dynamical equations are derived, which describe the space-time development of second-order coherence tensors of a quantized electromagnetic field in vacuo. With the help of these equations, laws for the conservation of correlations are obtained. Some new non-negative-definiteness conditions which the coherence tensors obey are also established.Keywords
