I will give the promised concluding part of an advanced class I gave
last term on work with Tingxiang Zou, though assuming no memory of the
first talk. I will briefly recall our conjectural description of
non-expansion for families of birational maps, then focus on the ("de
Jonquières") case of the action of the multiplicative group of unary
rational functions on the plane by (x,y) |-> (x,f(x)*y), and similar
situations.
