Jacobi equation for field theories and a geometric variational description of dissipation
David Martin de Diego, Najma Mosadegh
In this paper we give a geometric description of the Jacobi equations associated to a first-order Lagrangian field theory using a prolongation of the Lagrangian on a -cosymp…
Survey on the Biharmonic Hypersurfaces in Terms of the Induced Metric of Tensor Ricci
Najma Mosadegh, Esmaiel Abedi
In this article, we study the biharmonic hypersurfaces in the Sasakian space form with the induced metric of tensor Ricci. We find the existence necessary and sufficient condition…
Biharmonic Hypersurfaces With The Recurrent Operators In The Euclidean Space
Najma Mosadegh, Esmaiel Abedi
We show how some of well-known recurrent operators such as recurrent curvature operator, recurrent Ricci operator, recurrent Jacobi operator, recurrent shape and Weyl operators hav…
The Variational Geometry of Surfaces in the Conformally Flat Space
Najma mosadegh, Esmaiel Abedi
In this paper, close surfaces are considered in 3-dimensional harmonic conformally flat space in point of the variation. It is shown that if the conformal vector field be tangent t…
Biharmonic CMC Hypersurfaces in the Warped Product Space
Najma Mosadegh, Esmaiel Abedi
We find the necessary and sufficient condition for the proper biharmonic CMC hypersurfaces in the special warped product space. Furthermore, we obtain that there exists no proper b…
