| Outline of Final Research Achievements |
Connecting topology to mathematical physics and number theory, we prove that specializations of cluster variables are identified with Alexander polynomials of 2-bridge knots in a joint work with Wataru Nagai, and get a result in arithmetic topology generalizing the reciprocity law about Riemann surfaces to 3-dimensional manifolds based on an analogy between foliated structures on 3-manifolds and number fields in a joint work with Junhyeong Kim, Masanori Morishita and Takeo Noda. Moreover, we introduce WRT functions, and prove that specializations of WRT functions to roots of unity are identified with WRT invariants for Seifert loops in a joint work with Hiroyuki Fuji, Kohei Iwaki and Hitoshi Murakami.
