| Research Abstract |
The head investigator Fujii obtained several results that concerns Artin groups. First, for each Artin monoid, Fujii concretely constructed its geodesic automatic structure and obtained a rational function expression of its growth function. Next, Fujii considers representatives of each elements of Artin groups in terms of its standard generator system and gave a necessary condition such that representatives are shortest with respect to the generator system.
