Numerical Experience with Iterative Methods for Equality Constrained Nonlinear Programming Problems.
We show that indefinitely preconditioned symmetric Krylov-subspace methods are very efficient for solving linearized KKT systems arising in equality constrained different forms (original system, null-space transformation, r...

Improving the Stability and Robustness of Incomplete Symmetric Indefinite Factorization Preconditioners
Sparse symmetric indefinite linear systems of equations arise in numerous practical applications. In many situations, an iterative method is the method of choice but a preconditioner is normally required for it to be effective. In t...

A word-formation oriented overview of words with numeral meaning II: indefinite numerals
The article follows the description of definitive numerals (part I) both in content and in form. The concept of three indefiniteness kinds is developed, i.e. indefiniteness in the strict sense, algebraic indefiniteness, dei...

Efficient iteration methods for complex systems with an indefinite matrix term
Complex valued systems with an indefinite matrix term arise in important such as the Maxwell's equation and for the Helmholtz equation. Complex systems with symmetric positive definite matrices can be solved readily by rewr...

Polish indefinites : Some puzzles
In this paper, I discuss several empirical and theoretical puzzles discovered in the course of research inspired by Joanna Błaszczak's work on Polish indefinites (Błaszczak 2001, 2008 in particular). Specifically, I examined certain non-triv...
