Irregular varieites with geometric genus one, theta divisors, and fake   tori
  We study the Albanese image of a compact K\"ahler manifold whose geometric genus is one. We prove that if the Albanese map is not surjective, then the manifold maps surjectively onto an ample divisor in some abelian variety, and in many cases the ample divisor is a theta divisor. With a further natural assumption on the topology of the manifold, we prove that the manifold is an algebraic fiber space over a genus two curve. Finally we apply these results to study the geometry of a compact K\"ahler manifold which has the same Hodge numbers as those of an abelian variety of the same dimension.
