Abstract We study general and complementarity properties of matrices which are either pseudomonotone or copositive star on a closed convex cone. In particular we show that if a matrix is pseudomonotone on the nonnegative orthant of R n , then it belongs to P 0 ∩ Q 0 . We also show that if a matrix T is copositive star on a closed convex cone K , then the linear complementarity problem LCP( T,K,q ) is solvable for all q in R n iff zero is the only solution of the (homogeneous) problem LCP( T,K… CONTINUE READING
