Abstract

We revisit Koiso's original examples of rigid infinitesimally deformable Einstein metrics. We show how to compute Koiso's obstruction to the integrability of the infinitesimal deformations on CPn×CP1\mathbb{CP}^{n}\times \mathbb{CP}^{1} using completely elementary complex differential geometry.
