"Solving polynomial equations and transcendental functions"
Abstract:
After a review of clasical formulas computing the complex roots of polynomial equations, I will introduce a class of functions, called "theta-functions" which has remarkable properties. In particular, they allow to solve a general polynomial equation. Then, one will look at generalizations of these functions coming from mathematical physics, precisely from conformal field theory.
