Algorithmic and Geometric Topics Around Free Groups and Automorphisms

权宜之计

Hyperbolic Structures on Surfaces and Geodesic Currents,on of the compactification of Teichmüller space. Finally, in Section 3.5 we will present some generalizations of the notion of geodesic currents to other settings, such as negatively curved metrics on surfaces, flat metrics on surfaces, and free groups.

Over the past decades a wide range of other characterizations of context-free groups have been found. It underlines that context-free groups play a major role in combinatorial group theory.
