Аннотация

We consider Einstein-Maxwell-dilaton gravity with charged dust and interaction of the form PðχÞFμνFμν, where PðχÞ is an arbitrary function of the dilaton field χ that can be normal or phantom. For any regular PðχÞ, static configurations are possible with arbitrary functions g00 ¼ expð2γðxiÞÞ (i ¼ 1, 2, 3) and χ ¼ χðγÞ, without any assumption of spatial symmetry. The classical Majumdar-Papapetrou system is restored by putting χ ¼ const. Among possible solutions are black-hole (BH) and quasi-blackhole (QBH) ones. Some general results on BH and QBH properties are deduced and confirmed by examples. It is found, in particular, that asymptotically flat BHs and QBHs can exist with positive energy densities of matter and both scalar and electromagnetic fields.
