Abstract
Topology-changing transitions between vacua of different effective dimensionality are studied in the context of a 6-dimensional Einstein-Maxwell theory. The landscape of this theory includes a de Sitter vacuum (), a number of and vacua, and a number of vacua. We find that compactification transitions occur through the nucleation of electrically charged black hole pairs, and transitions from to and occur through the nucleation of magnetically charged spherical black branes. We identify the appropriate instantons and describe the spacetime structure resulting from brane nucleation.
