DESCRIPTION:We will explain the Bellman function approach to w
eighted singular integrals. We show how this techn
ique (non-linear PDE at heart) allows us to get ma
ny recent results in the theory. Such as the solut
ion of $A_2$ conjecture (and $A_2--A_\\infty$ vari
ant)\, the solution of the bump conjecture (and it
s one-sided variant)\, and also new results about
entropy and weighted estimates.\nWe also show how
this PDE approach allows us to build counterexampl
es to weak Muckenhoupt conjecture and some of its
relatives
