Spherically symmetric black holes in Kaluza–Klein unification.

Exact time-independent spherically symmetric black hole solutions of the (4+3)-dimensional Kaluza–Klein theory are obtained by imposing the isometry group E2 on the unified metric. The solutions include the five-dimensional Dobiasch–Maison–Lee solutions as a special case. The physical implication of the solutions is discussed. [ABSTRACT FROM AUTHOR]
