英文摘要
When n=1, 2 and 3, we construct a pair of transverse knots S and T satisfying the following properties (1)-(4) ;(1) S(n) is obtained from a transverse knot S by n stabilizations,(2) the topological knot type of T is the same as that of S(n),(3) the self-linking number of T is equal to that of S(n), and(4) T is not transversely isotopic to S(n).A topological knot type satisfying the above properties (2)-(4) is called "transversely non-simple." It was not known whether there exist transversely non-simple knot types until recently. In particular, this is the first example of a pair of transversely non-simple knots such that one of the pair admits at least two destabilizations.
