    • Stable Finite Elements for Problems With Wild Coefficients 

      Vavasis, Stephen A. (Cornell University, 1993-06)
      We consider solving an elliptic boundary value problem in the case that the coefficients vary by many orders of magnitude over the domain. A linear finite element method is used. It is shown that the standard method for ...
    • Stable Numerical Algorithms for Equilibrium 

      Vavasis, Stephen A. (Cornell University, 1992-09)
      An equilibrium system (also known as a KKT system, a saddle- point system, or a sparse tableau) is a square linear system with a certain structure. G. Strang has observed that equilibrium systems arise in optimization, ...
