Hypersphere and the Third Laplace-Beltrami Operator

Abstract

In this work, we examine the differential geometric objects of the hypersphere h in four dimensional Euclidean geometry E^4. Giving some notions of four dimension, we consider the ith curvature formulas of the hypersurfaces of E^4. In addition, we reveal the hypersphere satisfying ?^III h=Ahfor some 4×4 matrix A.
