Takeo Uramoto (Tohoku University), Recent developments in algebraic language theory
The purpose of this talk is to introduce a recent (2008~) active research trend in algebraic language theory. This field, among other approaches to formal languages, is characterized by its methodology: one reduces combinatorial / logical problems on formal languages (say, regular languages) into some tractable problems on algebraic structures (resp., finite semigroups). Recent works in the last decade shed new lights on this field (or its methodology) from the viewpoint of Stone-type duality theorem; and most importantly, indicated several new research directions extending classical frameworks. In this talk, based on our own works, we introduce this research trend (and its background motivation) and then carefully discuss its possible future directions.
