Let P - {p1,p2,. . . ,pn} be an independent point-set in Rd (i.e., there are no d + 1 on a hyperplane). A simplex determined by d + 1 different points of P is called empty if it contains no point of P in its interior. Denote the number of empty simplices in P by fd(P). Katchalski and Meir pointed out that . Here a random construction P n is given with , where K(d) is a constant depending only on d. Several related questions are investigated.
