SUMMARY:Pavel Zatitskii (ENS Paris\, SPbSU and PDMI RAS): Integral function
 als on BMO and Bellman function
DESCRIPTION:Pavel Zatitskii: In this talk we develop the method of finding 
 sharp estimates by using a Bellman function. In such a form the method app
 ears in the proofs of the classical John--Nirenberg inequality and Lp esti
 mations of BMO functions. In the present paper we elaborate a method of so
 lving the boundary value problem for the homogeneous Monge--Ampère equati
 on in a parabolic strip for sufficiently smooth boundary conditions. In su
 ch a way we have obtained an algorithm of constructing an exact Bellman fu
 nction for a large class of integral functionals in the BMO space.\nhttps:
