| Abstract: | I will firstly give an overview of arithmetic topology, which investigates the interaction between 3-dimensional topology and number theory. Then I will take up two fundamental questions in the subject. One is the question in 3-dim. topology ``what is a topological analog of the set of all primes ?", suggested by number theory. The other is the question in number theory ``what are arithmetic analogues of Witten invariants ?", suggested by 3-dim. topology. I will discuss some of recent progress on these questions. |
