Outline of Final Research Achievements

We found various properties of arithmetic functions arising from Galois representations in arithmetic fundamental groupoids. We investigated behaviors of Galois-polylogarithmic functions and derived a formula that relates their normalized special values on p-adic inertia group with standard p-adic polylogarithmic values. Elaborating the composition law for the Eisenstein invariants of universal monodromy representation in affine elliptic curves, we established a new foundation toward subsequent studies in arithmetic Galois monodromy theory.

Academic Significance and Societal Importance of the Research Achievements

絶対ガロア群に含まれる様々な数論的情報が,代数多様体のエタール的path空間への作用を通じて,どのように発現しているかを整数論・保形関数論のほか位相幾何学・表現論・組合せ群論の手法を援用して探究する.多重ゼータ値・多重ポリログ関数や一般化デデキント和などの数論的不変量に対する副有限群論的な解釈を通じて,整数論の新しい局面を切り開いた.
