| Research Abstract |
We have studied spatial graphs from a viewpoint of the concept multiplicity. We have define the concept multiplicity on a category. As an example, we defined a multiplicity of a knot over another knot. For a continuous map from a three-dimensional Euclidean space to the three-dimensional Euclidean space that maps a knot to another knot, we studied their knot types.
