On generalized $\hat{I}¾$-Parallel Maps

Abstract

In this paper, we introduce and study the notion of generalized $\hat{I}¾$-parallel maps between Riemannian manifolds, where $\hat{I}¾$ is a vector field on the target manifold. We define the associated energy functional and derive its first variation formula, leading to the Euler--Lagrange equation characterizing generalized $\hat{I}¾$-parallel maps. We establish fundamental properties of this new class of maps and investigate its relationship with harmonic and biharmonic maps. Furthermore, we study generalized $\hat{I}¾$-parallel curves in space forms and examine generalized $\hat{I}¾$-parallel submanifolds of space forms admitting concircular vector fields.
