Abstract

In this paper, we introduce $fL_k$-energy functionals; and by deriving variations of these functionals, we define $fL_k$-harmonic maps between Riemannian manifolds. Hereafter, by using these definitions, we introduce $fL_k$-harmonic morphisms, and then we find a relation between $fL_k$-harmonic maps and $fL_k$-harmonic morphisms.
