Branes and wrapping rules

TL;DR

This paper demonstrates that the branes in ten-dimensional IIA/IIB string theory follow specific wrapping rules during compactification, implying the existence of generalized Kaluza-Klein monopoles to match supergravity predictions.

Contribution

It introduces specific wrapping rules for branes in IIA/IIB string theory that are necessary for consistency with supergravity, suggesting new generalized monopoles.

Findings

Wrapping rules reproduce the correct number of supersymmetric branes.

Generalized Kaluza-Klein monopoles are implied by these rules.

Consistency with supergravity analysis is achieved.

Abstract

We show that the branes of ten-dimensional IIA/IIB string theory must satisfy, upon toroidal compactification, specific wrapping rules in order to reproduce the number of supersymmetric branes that follows from a supergravity analysis. The realization of these wrapping rules suggests that IIA/IIB string theory contains a whole class of generalized Kaluza-Klein monopoles.
