SUMMARY:Rank gradient in profinite groups - Nikolay Nikolov (University of
  Oxford)

DESCRIPTION:In this talk I will focus on the growth of generators in open 
 subgroups of profinite groups. In the case of abstract groups this topic h
 as received a lot of attention but in the profinite situation there are no
 t many results and they tend to be different from those for abstract group
 s. For example a pro-p group of positive rank gradient must have a dense f
 ree subgroup. As far as I know the analogous question for profinite groups
  is still open.<br>
