タイトル：Delta link-homotopy on spatial graphs
アブストラクト：
Delta link-homotopy is an equivalence relation on oriented
links generated by delta moves on the same component and ambient
isotopies, and extended to spatial graphs naturally. In this talk, we
will explain the content of the following papers.

Complut. 15 (2002), 543-570.

graphs on four vertices, to appear in J. Knot Theory Ramifications.
