Abstract: A diagram of a knot, a link or a spatial graph is a projection of it into the 2-sphere with over/under information at the every double points. In this talk we introduce a notion of a pseudo diagram which is a projection with over/under information at some double points of it. We discuss whether or not we can determine the triviality or the non-triviality of the knot from the pseudo diagram. I talk about its related topics.
