| Description | We construct the Einstein equation for an invariant Riemannian metric on the exceptional full flag manifold M = G(2)/T. By computing a Grobner basis for a system of polynomials on six variables we prove that this manifold admits exactly two non-Kahler invariant Einstein metrics. Thus G(2)/T turns out to be the first known example of an exceptional full flag manifold which admits a non-Kahler and not normal homogeneous Einstein metric. |
