Outline of Final Research Achievements

Recently study on projections (shadows) is active in knot theory and spatial graph theory. The head have introduced the notion of pseudo diagrams. We expanded this notion and made tables of knot shadows with a few double points. We defined knot invariants to knot shadows and forwarded unknotting numbers of positive knots.
We convened classes for elementary school students and events for people at large.
