Estimates of stiffness and stability for minimal subvarieties in the hyperbolic space
hyperbolic space; minimal submanifolds; second fundamental form; Simon's formula; super-stability.
This work presents a brief study on minimal isometric immersions in the hyperbolic space $\mathbb{H}^{n+m}$. The main objective is to demonstrate Simons' formula for the Laplacian $\triangle |A|$ of the second fundamental form norm and to use this formula to prove rigidity theorems that determine under what conditions a minimal submanifold of the hyperbolic space is totally geodesic. In addition, we will also define the concept of super-stability on minimal submanifolds and use Simons' formula to prove estimates for the first eigenvalue of the stability operator $\bar\lambda_1(M)$ of these minimal embeddings.
