TitleNon-identical twin groups of virtual knot
Every virtual knot has a pair of groups called the upper and lower groups of the knot. In this talk, we give a sufficient condition for a pair of groups which are realized by a certain virtual knot as the upper and lower groups. This is a joint work with Y. Nakanishi, S. Satoh, Y. Tomiyama.
