Title: Cohomological uniqueness of solutions of the Cauchy problem for the Einstein equation

Abstract:
The talk will discuss the Cauchy problem for the Einstein equation in the case of non-characteristic initial hypersurface. An additional condition on the initial data that allows to construct cohomologically unique formal solution of this problem in a neighborhood of initial hypersurface will be presented.
