S.B. Karavashkin Transformation of divergence theorem in dynamical fields (302K, Postscript) ABSTRACT. In this paper we will study the flux and the divergence of vector in dynamical fields, on the basis of conventional divergence definition and using the conventional method to find the vector flux. We will reveal that in dynamical fields the vector flux and divergence of vector do not vanish. In the terms of conventional EM field formalism, we will show the changes appearing in dynamical fields.
