In this paper we introduce and analyse a new Schur complement approximation based on incomplete Gaussian elimination. The approximate Schur complement is used to develop a multigrid method. This multigrid method has an algorithmic structure that is very similar to the algorithmic structure of classi
## Abstract This exposition presents a method for incorporating a technique known as βsplitting the bumpβ within an elimination form reinversion algorithm. This procedure is designed to reduce fillβin during reinversion and should improve the efficiency of linear programming systems which already u
## Abstract We show that if __G__ is a Ramsey sizeβlinear graph and __x,y__ β __V__ (__G__) then if we add a sufficiently long path between __x__ and __y__ we obtain a new Ramsey sizeβlinear graph. As a consequence we show that if __G__ is any graph such that every cycle in __G__ contains at least
