The Stability of $\alpha -$ Harmonic Maps with Physical Applications

The first result in this study is a non-existence theorem for $\alpha -$harmonic mappings. Additionally, a direct connection between the $\alpha -$ harmonic and harmonic maps is made possible via conformal deformation. Second, the instability of non-constant $\alpha$-harmonic maps is investigated with regard to the target manifold’s Ricci curvature requirements. Next, the concept of $\alpha -$stable manifolds and their physical applications are explored. Finally, it is investigated the $\alpha -$stability of compact Riemannian manifolds that admit a non-isometric conformal vector field as well as the Einstein Riemannian manifolds under certain assumption on the smallest positive eigenvalue of its Laplacian operator on functions.
