Closed String Tachyon Condensation: An Overview
arXiv:hep-th/0405064 · doi:10.1088/0264-9381/21/10/027
Abstract
These notes are an expanded version of a review lecture on closed string tachyon condensation at the RTN workshop in Copenhagen in September 2003. We begin with a lightning review of open string tachyon condensation, and then proceed to review recent results on localized closed string tachyon condensation, focusing on two simple systems, C/Z_n orbifolds and twisted circle compactifications.
