Black holes in multidimensional theory with Ricci plane internal spaces

A generalization of the solution of Tangherlini 1] to the case of internal Ricci plane spaces is obtained. It is shown that a horizon exists in the (2 + d)-dimensional section only in the trivial case where the scale factors of the internal spaces are constant. The p-adic analog of the solution is considered.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 62–65, September, 1991.
