Mordell-Lang and Manin-Mumford in positive characteristic, revisited

Anand Pillay

We give a reduction of function field Mordell-Lang to function field Manin-Mumford, in positive characteristic. The upshot is another account of or proof of function field Mordell-Lang in positive characteristic, avoiding the recourse to difficult results on Zariski geometries.

(This work is joint with Benoist and Bouscaren.)

This is the second of two distinct talks given by this speaker on October 31.
