Abstract
In this article, we prove, under certain conditions, the connectedness of sets of the form {x: f(x, y) = 0, y ∈ E} where f is a function with x varying over an open set in R n and the parameter y varying over a topological space. Based on this, we show that the partitioned matrix
is (LCP) connected (i.e., for all q, the solution set of LCP(q, M) is connected) when A ∈ P 0 ∩ Q, C = 0, and D is connected. We also show that (a) any nonnegative P 0 ∩ Q 0-matrix is connected and (b) any matrix M partitioned as above with C and D nonnegative, and A ∈ P 0 ∩ Q is connected.
