摘要：
The present work focuses on the scalax and electromagnetic fields in a spatially closed FRW Universe with incoherent dust. First, as the complex scalax field is under consideration, we derive the general solutions of the Gordon equation, in terms of the positive-frequency-like parity modes, and the corresponding propagator. Secondly, we turn to the source-free Maxwell equations in order to find a (1 + 4)-parametric class of closed form solutions representing a non-propagating fundamental electric field and a burst of electromagnetic radiation.
