This is an in-person seminar at BIMSA over lunch, aimed to promote communications in the Number Theory teams at BIMSA and YMSC. Each talk is 45 minutes long and does not focus on research results. Instead, we encourage each speaker to discuss either (1) a basic notion in Number Theory or related fields or (2) applications or computational aspects of Number Theory. People interested in Number Th...
Abstract:In the study of mixed elliptic motives, we noticed the importance for rational K\pi 1 property on some bar complex arising from mixed elliptic motives. Since its bar complex is some what complicated, it will be useful to consider some easier case, the case for Riemann surfaces.Rational fundamental group of Riemann surface is desribed by Sullivan's old paper, but it seems that rational...
