TitleVirtual graph presentations of ribbon surface-knots
Abstract
In our previous study, we introduced a method to describe a ribbon $S^2$- or $T^2$-knot by use of a virtual arc or knot diagram, respectively. We generalize this method to a ribbon surface-knot with a virtual graph diagram, and study the stable equivalence of ribbon presentations in terms of virtual graph diagrams.
