عنوان On the harmonic vector elds نوع پژوهش مقاله ارائه شده کلیدواژهها Energy functional, Isotropic almost complex structure,Tangent bundle, Tension field چکیده An isotropic almost complex structure J; defines a Riemannian metric g; on the tangent bundle which is the generalized type of the Sasaki metric. In this paper, the harmonic maps defined by vector fields are studied where the tangent bundle will be equipped with the metric g;. پژوهشگران امیر باغبان (نفر اول)، اسمعیل عابدی (نفر دوم)
