Colloquium: Monday, December 4, 4 pm. Speaker: Yochay Jerby (Hebrew University). Title: “Fermat’s last theorem – an elementary approach”.

The aim of this talk is to present an elementary approach
to Fermat’s last theorem. We translate the condition of (x,y,z) being
solution of Fermat’s equation x^n+y^n=z^n to a robust system of
p-adic recursion relations (to which we refer as “zipper equations”).
For n=3 we will show that the zipper relations admit no solution. The
talk will be followed with illustrations.
