The proposed PhD project for Raya Valentinova Mancheva is on the investigation of the behaviour of matter fields near spherically symmetric weak null singularities inside black holes and their back-reaction on the gravitational field. In a first step the spherically symmetric Euler equations and elasticity will be considered on a fixed background and the temporal behaviour of the state variables determined. In a more challenging second step, the coupling to the spherically symmetric Einstein-Maxwell-scalar field system is taken into account to determine the fate of the weak null singularity under the presence of those matter fields.

Raya Valentinova Mancheva的博士项目是研究黑洞内球对称弱零奇点附近物质场的行为及其对引力场的反作用。在第一步，球对称欧拉方程和弹性将考虑在一个固定的背景和状态变量的时间行为确定。在更具挑战性的第二步中，考虑到与球对称爱因斯坦-麦克斯韦-标量场系统的耦合，以确定在这些物质场存在下弱零奇点的命运。
