| Outline of Final Research Achievements |
The Artin L-functions are meromorphic functions associated with Galois representations of number fields. Stark's conjecture states an explicit formula for the leading terms of the Taylor expansions of the Artin L-functions.
The purpose of my research is to study Stark's conjecture by a new method. That is, by using Stark units, CM-periods, the multiple gamma function, and their p-adic analogues simultaneously, we tried to solve this problem. Each of them, or, the relation between two of them has been studied well so far. Recently, we provided an alternative proof of Stark's conjecture when the base field is the rational number field. Moreover we obtained some partial results concerning its generalization and submitted some papers.
