Brane solitons for G2 structures in eleven-dimensional supergravity revisited

Show affiliations


We investigate the four-dimensional supergravity theory obtained from the compactification of eleven-dimensional supergravity on a smooth manifold of G2 holonomy. We give a new derivation for the Kähler potential associated with the scalar kinetic term of the N = 1 four-dimensional theory. We then examine some solutions of the four-dimensional theory which arise from wrapped M-branes.
