Using incomplete indefinite $L D L^{T}$ preconditioning for inexact interior point methods for linear programming

Robert Luce

Most linear algebra kernels in interior point methods for linear programming require the solution of linear systems of equation with the matrix $N = A^{T} D^{- 1} A$ (or $A D^{- 1} A^{T}$ ),…

The index of singular zeros of harmonic mappings of anti-analytic degree one

Robert Luce, Olivier Sète

We study harmonic mappings of the form $f (z) = h (z) - z$ , where $h$ is an analytic function. In particular we are interested in the index (a generalized multiplicity) of…
