Introduction to G2 geometry
The classification of Riemannian manifolds with special holonomy contains two “exceptional” cases: G2 and Spin(7). In this course, I will focus on the G2 case and introduce various topics.
We start from the linear algebra in G2 geometry. Then we study topics such as the torsion of a G2-structure, topological properties of compact manifolds with holonomy contained in G2, the moduli theory, and calibrated geometry.
