Abstract: We consider spatial graphs as a generalization of knots and links in the three-space. A regular projection is a regular diagram without over/under information at crossing points. From a regular projection we have several spatial graphs by adding over/under informations to the crossing points. We say that the regular projection is identifiable if all of them are mutually ambient isotopic. We study identifiable projections of spatial graphs and related topics in knot theory.
