| Abstract | |
We prove that there are no regular algebraic hypersurfaces with non-zero constant mean curvature in the Euclidean space Rn+1, n >= 2, defined by polynomials of odd degree. Also we prove that the hyperspheres and the round cylinders are the only regular algebraic hypersurfaces with non-zero constant mean curvature in Rn+1, n >= 2, defined by polynomials of degree less than or equal to three. These results give partial answers to a question raised by Barbosa and do Carmo. (AU) | |
