Ultimate approximations in nonmonotonic knowledge representation systems

open access: yes, 2002
We study fixpoints of operators on lattices. To this end we introduce the notion of an approximation of an operator. We order approximations by means of a precision ordering. We show that each lattice operator O has a unique most precise or ultimate approximation. We demonstrate that fixpoints of this ultimate approximation provide useful insights into

A second derivative SQP method: local convergence [PDF]

open access: yes, 2008
In [19], we gave global convergence results for a second-derivative SQP method for minimizing the exact ℓ1-merit function for a fixed value of the penalty parameter. To establish this result, we used the properties of the so-called Cauchy step, which was

Instability of nonsymmetric nonmonotone equilibria of the Vlasov-Maxwell system [PDF]

open access: yesJournal of Mathematical Physics, 2011
We consider the \documentclass[12pt]{minimal}\begin{document}$1\frac{1}{2}$\end{document}112-dimensional relativistic Vlasov-Maxwell system that describes the time-evolution of a plasma. We find a relatively simple criterion for spectral instability of a wide class of equilibria.
