SUMMARY:Asymptotically (anti) de Sitter Black Holes and Wormholes with a S
 elf Interacting Scalar Field in Four Dimensions - Andres Anabalon Dupuy (U
 niversidad Adolfo Ibanez\, Chile)

DESCRIPTION:The aim of the talk is to report on the existence of a wide va
 riety of exact solutions\, ranging from black holes to wormholes\, when a 
 conformally coupled scalar field with a self interacting potential contain
 ing a linear\, a cubic and a quartic self interaction is taken as a source
  of the energy-momentum tensor\, in the Einstein theory with a cosmologica
 l constant. Among all the solutions there are two particularly interesting
 . On the one hand\, the spherically symmetric black holes when the cosmolo
 gical constant is positive\; they are shown to be everywhere regular\, nam
 ely there is no singularity neither inside nor outside the event horizon. 
 On the other hand\, there are spherically symmetric and topological wormho
 les that connect two asymptotically (anti) de Sitter regions with a differ
 ent value for the cosmological constant.
