When he visited Barcelona, Adrian Mathias got interested in questions regarding the relation of attack considered by dynamicists. Given a self-mapping of a topological space, a point x attacks y, or y is an omega-limit point of x, if y is a cluster point of the sequence of iterates of x. He successfully applied set-theoretical ideas in the study of this relation. We shall describe some of his contributions to the subject.
