| Research Abstract |
Cusp forms on the complex upper half plane have been studied for the connection with number theory. The feature of our research is focusing on natural correspondences between cusp forms, periods and Dedekind symbols. We have introduced the notion of elliptic Apostol-Dedekind sums and showed these sums generate Dedekind symbols with polynomial reciprocity laws. We also studied how we can apply these sums to knot theory.
