Resumen de Scharlemann-Thompson invariant for knots with unknotting tunnels and the distance of (1,1)-splittings

Toshio Saito

• Scharlemann and Thompson introduced an invariant for the pair of a knot in the 3-sphere and an unknotting tunnel for . The paper studies the relationship between the invariant of a (1,1)-knot and the distance of its (1,1)-splitting introduced by the author.
