Abstract
The purpose of the present paper is to find the necessary and sufficient condition for the special (α, β)−metric L = (b1α2+b2αβ+b3β2) / (a1α+a2β) to be an Einstein metric. Here α is a Riemannian metric and β is a constant Killing one-form.
Keywords and phrases. (α, β)−metric, constant Killing, spray curvature etc.
