| Abstract: | Using the method of Moving frames this paper has proved P.Verheyen and L.Verstraelen's Theorem on the locally symmetric affine hypersufaces: Let M be a nondegenerate of An 1 with n>2.Then M is affine locally symmetric w. r. t the induced connection if and only if M is an improper affine hypersphere or a nondegenerate quadratic gypersurface. |
