Largeness, Rank Gradient and how these relate to Deficiency and p-Deficiency of finitely presented (and generated where appropriate) groups

If you have a question about this talk, please contact Joanna Fawcett .

We will go over the notions of deficiency for finitely presented groups and p-deficiency (p a prime) of finitely generated groups. We sill see how these notions are related to strong group properties which non-abelian free groups have, such as being large and having positive rank gradient.
