Towards a version of non-commutative geometry, one may consider (non-commutative) infinite Hopf algebras with some condition on the growth. Between different options, the Gelfand-Kirillov dimension seems a nice notion of growth to take into account.

Starting from the basic definitions and examples, we will report some recent results on the classification of pointed Hopf algebras with finite Gelfand-Kirillov dimension.
