Abstract

A study is made of R 6 as a singular quotient of the conical space R +×CP 3 with holonomy G 2, with respect to an obvious action by U(1) on CP 3 with fixed points. Closed expressions are found for the induced metric, and for both the curvature and symplectic 2-forms characterizing the reduction. All these tensors are invariant by a diagonal action of SO(3) on R 6, which can be used effectively to describe the resulting geometrical features.
