1. INTRODUCTION AN ORIENTED link L is said to be positive if L has a diagram with no negative crossing. Many interesting features have been detected in various invariants of such positive links. For instance, signatures of them must be negative Cl, 9, 10, ll] and the Conway polynomials of them are always positive [2]. In addition to these results, we will establish a curious correspondence in the skein and Kauffman polynomials of positive links. To state this new result, we will prepare several notations. positive
