Abstract
I will discuss crossing symmetric dispersion relations and its applications. 1) In QFT I will derive two sided bounds on Wilson coefficients in a low energy effective expansion of 2-2 scattering. I will also show an intriguing connection with the Bieberbach conjecture in mathematics. 2) In CFT, I will show a rigorous derivation of the Polyakov bootstrap which will enable us to fix the contact terms in the Witten diagram basis expansion.
