growth function of a finitely generated group measures how fast the balls in its Cayley graphs grow.
<br>
This asymptotic invariant attracted a lot of attention starting from Milnor's questions and Gromov's theorem about groups which have polynomial growth.<br>
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<br>
is intermediate between polynomial and exponential. We will outline results related to generic growth in a family of groups of intermediate growth constructed by R. Grigorchuk.<br>

Time: 15.40,<br>
