Estimates for the Nash-Sofer preconditioner for the reduced Hessian for some elliptic variational inequalities

*SIAM JOURNAL ON OPTIMIZATION*, *9*(2), 327–341.

author keywords: preconditioners; reduced Hessian; elliptic variational inequalities

TL;DR:
A class of examples is presented to show how the quality of the Nash--Sofer preconditioner can be directly estimated and one consequence is that if the Hessian is the five-point discretization of a certain type of strongly elliptic operator with homogeneous Dirichlet boundary conditions on an $n \times n$ mesh, then the condition number of the reduced Hessian can be lowered.
