E11, generalised space-time and IIA string theory; the R-R sector

TL;DR

This paper extends the non-linear realisation of E11 and l1 to include R-R sector fields at level one, broadening the understanding of space-time symmetries in IIA string theory.

Contribution

It introduces the R-R sector into the E11 non-linear realisation framework at level one, expanding previous models that only included NS-NS fields.

Findings

Inclusion of R-R fields at level one in E11 framework

Enhanced understanding of IIA string theory symmetries

Extension of non-linear realisation to higher levels

Abstract

We extend the analysis of arXiv:1009.2624, which constructed the non-linear realisation of the semi-direct product of E11 and the l1 representation at level zero, to level one. Thus we add to the previously considered NS-NS fields those of the R-R sector.
