运动Dyon粒子双矢势场方程的格林函数解

Green Function Solution to the Doublet Potential Equations of the Moving Dyons

首先回顾了有磁荷(或等效磁荷)存在的情况下电磁场双四维势的描述方法,给出了场强与双四维势的关系以及具有电磁对偶对称性的Maxwell方程;利用Green函数法求出了场方程具有Lorentz变换协变性的推迟解;最后给出了广义李纳-魏谢尔势的表述形式.

After reviewing the double 4 dimensional potentials of the electromagnetic field theory in the presence of magnetic charge （or effective magnetic charge）, we give out the electromagnetic （EM） duality symmetric Maxwell equations and the relationship between the field strength and the double potentials. Then by using the Green function method we find the Lorentz invariant retarded solutions of the field equations, and finally obtain the explicit expressions of the generalized Lienard-Wiechert potentials.
