## Idea

A G2-manifold with conical singularities is also called a $G_2$-conifold.

### $G_2$-conifolds

Three simply connected $G_2$-cones are known: the

1. metric cone on complex projective 3-space

2. metric cone on $S^3 \times S^3$

3. metric cone on $SU(3) / (U(1) \times U(1))$

More on the metric cone over complex projective 3-space as a G2-manifold:
