Abstract
We introduce the notion of $V$-minimality, for $V$ a smooth vector field on a Riemannian manifold. This is a natural extension of the classical notion of minimality which is achieved for $V=0$. Complex submanifolds in a locally conformal K\"ahler manifold are $V$-minimal, for $V$ a suitable integer multiple of the Lee vector field. To emphasis the utility of this notion we extend some results from \cite{AAB}. Specifically, we prove that a PHH submersion is $V$-harmonic if and only if it has minimal fibres and a PHH $V$-harmonic submersion pulls back complex submanifolds to $V$ minimal submanifolds.
