摘要：
A least-squares method based on the first-order velocity-pressure-vorticity formulation for the Stokes problem is proposed. This method leads to a minimization problem rather than to a saddle-point problem. The choice of the combinations of elements is thus not subject to the Ladyzhenskaya-Babuška-Brezzi (LBB) condition. Numerical results showing the optimal rate of convergence for equal-order interpolations are given. © 1990.
