10D Massive Type IIA Supergravities as the uplift of Parabolic M2-brane Torus bundles

TL;DR

This paper explores how two 10D massive type IIA supergravities are derived from M2-brane torus bundles with parabolic monodromy, linking supergravity deformations to specific M2-brane compactifications.

Contribution

It establishes a connection between the two known massive deformations of type IIA supergravity and the uplift of M2-brane torus bundles with parabolic monodromy.

Findings

Romans supergravity corresponds to M2-brane on a twice-punctured torus bundle.

The two supergravities are associated with linearly and non-linearly realized parabolic monodromies.

The work provides a geometric interpretation of massive deformations in terms of M2-brane compactifications.

Abstract

We remark that the two 10D massive deformations of the $N=2$ maximal type IIA supergravity (Romans and HLW supergravity) are associated to the low energy limit of the uplift to 10D of M2-brane torus bundles with parabolic monodromy linearly and non-linearly realized respectively. Romans supergravity corresponds to M2-brane compactified on a twice-punctured torus bundle.
