    Proof of the Lee-Yang and Griffiths-Nishimori Theorems.

    Résumé : The Lee-Yang Theorem (1952) asserts that the zeros of a certain class of polynomials (partition functions for the ferromagnetic Ising model) lie on the unit circle. I will present a short proof of this amazing theorem, along with a beautiful extension by Griffiths and Nishimori (1983), which states that the zeros are all simple.
