How Groups Grow
M. Gökhan Benli
Middle East Technical University, Turkey
Özet : The growth function of a finitely generated group measures how fast the balls in its Cayley graphs grow. This asymptotic invariant attracted a lot of attention starting from M. Gromov's celebrated theorem about groups which grow polynomially. This talk will be a survey of history, open problems and recent developments around this notion. The main focus will be on groups whose growth is intermediate between polynomial and exponential constructed by R. Grigorchuk.
