Perold, André. "A Degeneracy Exploiting LU Factorization for the Simplex Method." In Large Scale Linear Programming, edited by G. B. Dantzig, M. A. H. Dempster, and Markku Kallio. Laxenburg, Austria: ...

Complex symmetric matrices whose real and imaginary parts are positive definite are shown to have a growth factor bounded by 2 for LU factorization. This result adds to the classes of matrix for which ...

In this paper, we consider the scattering problem of time-harmonic electromagnetic waves from an infinite cylinder having an open arc Г and a bounded domain D in ℝ² as cross section. We focus on the ...
