A mathematical model for planning oil products distribution via pipeline
Amir Baghban, Majid Yousefikhoshbakht
Compared to other transportation modes, road, railroad and vessel, multiproduct pipelines are the safest and most economical way of conveying petroleum products over long distances…
Finding Geodesics on Surfaces Using Taylor Expansion of Exponential Map
Esmaeil Peyghan, Esa Sharahi, Amir Baghban
Our aim in this paper is to construct a numerical algorithm using Taylor expansion of exponential map to find geodesic joining two points on a 2-dimensional surface for which a Rie…
Curvatures of metrics induced by the isotropic almost complex structures
Amir Baghban, Esmaeil Abedi
Isotropic almost complex structures induce a class of Riemannian metrics on tangent bundle of a Riemannian manifold. In this paper the curvature tensors of these metrics will be ca…
On the integrability of the isotropic almost complex structures and harmonic unit vector fields
Amir Baghban, Esmaeil Abedi
Aguilar introduced isotropic almost complex structures on the tangent bundle of a Riemannian manifold . In this paper, some results will be obtained on the integ…
Harmonicity of unit vector fields with respect to a class of Riemannian metrics
A. Baghban, E. Abedi
The isotropic almost complex structures induce a Riemannian metric on TM, which are the generalized type of Sasakian metric. In this paper, the Levi-Civita connection of…
