Title	The design and use of a sparse direct solver for skew symmetric matrices
Contributors	IS Duff (CCLRC Rutherford Appleton Lab.)
Abstract	We consider the direct solution of sparse skew symmetric matrices. We see that the pivoting strategies are similar, but simpler, to those used in the factorization of sparse symmetric indefinite matrices, and we briefly describe the algorithms used in a forthcoming direct code based on multifrontal techniques for the factorization of real skew symmetric matrices. We show how this factorization can be very efficient for preconditioning matrices that have a large skew component.
