... (Here we have used the fact that cvk + uk = Ukand wk are of the Same sign.) For all c sufficiently small and positive, e.g., such that cIviI < Iuil if ui # 0, we have S-(cv’ + u) 3 S-(u) = j. From the definition of c* and continuity properties of St and S-, it follows that K(c*v’+u)

... To study matrices in further detail, we will need to perform elementary row and column operations on them. If A ∈ Rm×n , any one of the following operations on the rows or columns of A is called an elementary row (resp. column) operation type 1: interchanging any two rows (resp. columns) of A type 2 ...
