초록 : I wll introduce an abelian modular symbol, which is nothing but a cohomology class with compact support on a punctured cylinder. Using the abelian modular symbol, a p-adic measure is defined and from this measure, we construct the a classical p-adic Dirichlet L-function. This is an abelian version of the famous modular symbol approach develpoed by Mazur and other mathematicians. After the introduction, related topics such as \mu-invariant of abelian number field and Iwasawa power series will be presented. This presentation is a repetition with minor modifications of previous one Delivered at Math dept of Postech number theory seminar.
