Abstract

In this talk we investigate the symmetry under E~10~ of Romans' massive type IIA supergravity. We show that the dynamics of a spinning particle in a non‐linear sigma model on the coset space E~10~/K(E~10~) reproduces the bosonic and fermionic dynamics of massive IIA supergravity, in the standard truncation. In particular, we identify Romans' mass with a generator of E~10~ that is beyond the realm of the generators of E~10~ considered in the eleven‐dimensional analysis, but using the same, underformed sigma model. As a consequence, this work provides a dynamical unification of the massless and massive versions of type IIA supergravitiy inside E~10~.
