Abstract

Some consequences of dimensional compactification for black holes in the context of d = 11 supergravity were discussed1,2,3 The new solutions exhibit novel features. Some of them have tightly dressed singularities, by which we denote a situation where the horizon coincides with a (light like) singularity. It leads to a new type of Penrose diagram from which one can see that there is only a single universe connected to the singularity. The fact that it is not possible to analytically extend the coordinates over the horizon implies that the Hawking temperature is undetermined. Within the set of ansatze which were studied, namely the time independent SO3 × SO8 symmetric metrics, no soliton type solutions were found.
