  abstract	= {A nonsymmetric formulation of saddle-point systems is
		  considered and symmetric part preconditioning of the
		  conjugate gradient method (CGM) is applied. Linear and
		  superlinear convergence estimates are derived for the
		  finite element solution of the Stokes problem and of
		  Navier's equations of elasticity.}
