项目摘要

I organized researches on invariants of knots and 3-manifolds.I edited the proceedings of the workshop "Invariants of Knots and 3-Manifolds", which I organized in September 2001, and published the proceedings from the journal Geometry and Topology Monographs. In particular, I edited a list of problems, which was made based on problems given in the problem sessions of the workshop, and published it as a part of the proceedings.I studied the loop expansion of the Kontsevich invariant, in particular, the 2-loop polynomial, which presents the 2-loop part of the loop expansion. I presented the 2-loop polynomial of a knot in terms of finite type invariants of a spine of a Seifert surface of the knot, from the viewpoint that I regard the 2-loop polynomial of a knot as an equivariant Casson invariant of the infinite cyclic cover of the knot complement. I obtained a bound of the degree of the 2-loop polynomial of a knot by twice the genus of the knot, by calculating the presentation concretely … More introducing Gaussian diagrams. Further, I gave explicit presentations of the 2-loop polynomial for the torus knots and the knots of genus 1. Furthermore, I showed a cabling formula for the 2-loop polynomial, which gives the 2-loop polynomial for any cable knot of a given knot.I organized a low-dimensional topology seminar, jointly with Kazuo Habiro, who is a co-investigator of this research. The speakers were Sergei Duzhin, Kazuhiro Hikami, Andrew Kricker, Julien Marche, Jean-Baptiste Meilhan, Gregor Masbaum, Jorgen Andersen, Yoshiyuki Yokota, Jozef Przytycki, and their talks were on advanced topics in the area of invariants of knots and 3-manifolds. In particular, by financial supports from the grant of this research, Kricker and Marche stayed at the RIMS in two weeks. I think their talks and stays were very good, from the viewpoint of joint researches between them and me and the co-investigator, and from the viewpoint of research interactions between them and young researchers such as graduate students.

我组织了调节和3个maniford的研究。I编辑了“结3个Manifolds的无害”研讨会，并于2001年9月组织了HO，并特别编辑了《几何学和拓扑》杂志。这是根据研讨会的问题进行的。我认为结的2循环圆环的圆环覆盖率是结合结的两倍的环。圆环结的2环多项式和属1的结构。演讲者与Kazuo Habiro共同的研讨会是Sergei Duzhin，Kazuhiro Hikami，Andrew Kricker，Andrew Kricker，Julian Marche，Jean-Baptiste Meilhan，Gregor Masbaum，Jorgen Andersen，Jorgen Andersen，Yoshiyuki，Yoshiyuki，Jozef Przytycki和他们的谈话和3个地区和3个地区。尤其是，通过这项研究的授予，克里克和马尔克在两周内保持了篮筐
