DESCRIPTION:Dawide Kielak\nWe will see how amenability of a group assists 
 one when working with its group \nring\, and also helps in working with g
 roup rings in general. We will introduce a \nnotion of the Newton polytop
 e of a matrix\, and see how it is relevant in the \nstudy of fibreings of
  3-manifolds\, and in general in the theory of \nBieri--Neumann--Strebel 
 invariants.
