The world is vastly becoming a completely digital one with most transactions carried out over the internet. This has exposed the internet to increasing threats and attacks and has necessitated the need for an internet-based authentication and authorization services. One Time Passwords (OTP) have been introduced to overcome the limitations of static passwords. However, research […]

Let M be an n-dimensional complete Riemannian manifold, we investigate the geometric nature of such M which admits any of the family of Sobolev-type inequalities with the optimal Euclidean Sobolev constant. This leads to several conditions under which M with nonnegative Ricci curvature is isometric to Euclidean space Rn https://eprints.lmu.edu.ng/id/eprint/2314
