Query: Gauss diagram formulas of Vassiliev invariants of spatial 2-bouquet
  graphs   We introduce new formulas that are Vassiliev invariants of flat vertex
isotopy classes of spatial 2-bouquet graphs, which are equivalent to 2-string
links. Although any Gauss diagram formula of Vassiliev invariants of spatial
2-bouquet graphs in a 3-space has been unknown, this paper gives the first and
simple example.
