		<abstract>A method to fit algebraic curves and surfaces using a data independent constraint invariant to rotations and translations is presented. This constraint corresponds to the generalization of the Bockstein constraint to algebraic curves of arbitrary order p > 1 in 2  D space, and algebraic surfaces of arbitrary order p > 1 in N-dimensional real space, with N > 3. The fitting is solved using standard eingenvector-eingenvalue results.</abstract>
