D-brane Charges in Five-brane backgrounds
Juan Maldacena, Gregory Moore, Nathan Seiberg
TL;DR
This paper explores the nature of discrete D-brane charges in five-brane backgrounds, interpreting them through Higgs mechanisms and boundary degrees of freedom, with implications for the AdS/CFT correspondence.
Contribution
It provides a novel interpretation of Z_k D-brane charges as arising from a Higgs mechanism and boundary singleton degrees of freedom.
Findings
Discrete Z_k D-brane charges can be extended to U(1) via boundary singletons.
The interpretation offers insights into the role of singletons in AdS/CFT.
The approach clarifies the topological and boundary aspects of D-brane charges.
Abstract
We discuss the discrete Z_k D-brane charges (twisted K-theory charges) in five-brane backgrounds from several different points of view. In particular, we interpret it as a result of a standard Higgs mechanism. We show that certain degrees of freedom (singletons) on the boundary of space can extend the corresponding Z_k symmetry to U(1). Related ideas clarify the role of AdS singletons in the AdS/CFT correspondence.
