| Research Abstract |
We introduced local moves on knots and links, called simple ribbonmoves and studied their effect on knots and links. Moreover, we extend the moves to aspecial kind of fusions, called simple ribbon fusions. We also studied their effect on knotsand links. In both cases we obtained results on genera of knots and links, and on primenessof knots. In the former topic, there are no difference between the statements on simpleribbon moves and simple ribbon fusions. However, in the latter topic, there is a differencein the exceptional cases.
