On the other hand, for the Stokes equation we consider here, the Schur -complement is $B^TA^{-1}B$ where the matrix $A$ is related to the +complement is $BA^{-1}B^T$ where the matrix $A$ is related to the Laplace operator (it is, in fact, the matrix corresponding to the bilinear form $(\nabla^s \varphi_i, \nabla^s\varphi_j)$). Thus, solving with $A$ is a lot more complicated: the matrix is badly
