本文研究了Einstein-Maxwell-Einstein理论中自引力复荷电标量场的动力学坍缩问题。我们还考虑了它的两个简化，即，幻影麦克斯韦场和幻影标量场在爱因斯坦引力的影响下分别坍缩。一个从规则时空开始，通过视界的形成和最后的奇点引导演化。我们讨论的结构中出现的动力学崩溃的过程中，并评论所考虑的领域在其过程中的作用。
We investigated the problem of the dynamical collapse of a self-gravitating complex charged scalar field in Einstein-Maxwell-dilaton theory with a phantom copuling for the adequate fields in the system under consideration. We also considered two simplifications of it, i.e., the separate collapses of phantom Maxwell and phantom scalar fields under the influence of Einstein gravity. One starts with the regular spacetime and leads the evolution through the formation of the horizons and the final singularity. We discuss the structures of spacetimes emerging in the process of the dynamical collapse and comment on the role of the considered fields in its course.
