The Fischer-Marsden Solutions on Almost CoK¨hler Manifold

Abstract

In this paper, we characterize the solutions of the Fischer-Marsden equationL*(?) = 0on ang aalmost CoK¨¨hler manifold. We prove that the Fischer-Marsden equation has only trivial solutionaon almost CoK¨¨hler manifold of dimension greater than3with?belonging to the(?, µ)-nullitydistribution and? < 0.
