Abstract
. We prove that every ( 2 n +1 )-dimensional η -Einstein contact metric manifold (i.e., the Ricci tensor S satisfies S = αg + βη ⊗ η for some smooth functions α, β ) with purely transversal Bach tensor is Einstein.
期刊介绍：
Annales Polonici Mathematici is a continuation of Annales de la Société Polonaise de Mathématique (vols. I–XXV) founded in 1921 by Stanisław Zaremba.
The journal publishes papers in Mathematical Analysis and Geometry. Each volume appears in three issues.
