OverviewPlease note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. High Quality Content by WIKIPEDIA articles! In differential geometry, a G2-structure is an important type of G-structure that can be defined on a smooth manifold. If M is a smooth manifold of dimension seven, then a G2-structure is a reduction of structure group of the frame bundle of M to the compact, exceptional Lie group G2. The property of being a G2-manifold is much stronger than that of admitting a G2-structure. Indeed, a G2-manifold is a manifold with a G2-structure which is torsion-free. The letter G occurring in the phrases G-structure and G2-structure refers to different things. In the first case, G-structures take their name from the fact that arbitrary Lie groups are typically denoted with the letter G . On the other hand, the letter G in G2 comes from the fact that the its Lie algebra is the seventh type ( G being the seventh letter of the alphabet) in the classification of complex simple Lie algebras by Elie Cartan.
