A subset S′ of S is termed a k-set of S if it contains k points and there exists a straight line which has no point of S on it and separates S′ from S−S′. We let fk(n) denote the maximum number of k-sets which can be realized by a set of n points. This paper studies the asymptotic behaviour of fk(n) as this function has applications to a number of problems in computational geometry. A lower and an upper bound on fk(n) is established. Both are nontrivial and improve bounds known before. In particular,  is shown by exhibiting special point-sets which realize that many k-sets. In addition,  is proved by the study of a combinatorial problem which is of interest in its own right."}],"scopus_import":"1","quality_controlled":"1","author":[{"full_name":"Edelsbrunner, Herbert","last_name":"Edelsbrunner","first_name":"Herbert","orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Welzl, Emo","last_name":"Welzl","first_name":"Emo"}],"intvolume":"        38","citation":{"chicago":"Edelsbrunner, Herbert, and Emo Welzl. “On the Number of Line Separations of a Finite Set in the Plane.” <i>Journal of Combinatorial Theory Series A</i>.
