Homogeneous almost K\"ahler manifolds and the Chern-Einstein equation

Abstract

Given a non compact semisimple Lie group $G$ we describe all homogeneous spaces $G/L$ carrying an invariant almost K\"ahler structure $(\omega,J)$. When $L$ is abelian and $G$ is of classical type, we classify all such spaces which are Chern-Einstein, i.e. which satisfy $\rho = \lambda\omega$ for some $\lambda\in\mathbb R$, where $\rho$ is the Ricci form associated to the Chern connection.
