A widespread solution-generating technique of general relativity consists of conformally transforming known “seed” solutions. It is shown that these new solutions always solve the …
We study a class of charged cosmological black holes defined by the Shah-Vaidya solution, which is similar to the McVittie solution but for a central object of nonzero electric charge. We …

A model universe is analyzed with N protons and electrons where there are electromagnetic and spin interactions in the Hamiltonian is investigated in the context of quantum shape …
