摘要: The goal of the present paper is two-fold. First, we review some recent progress concerning generalizations various classical results, such as sufficient conditions to guarantee univalence harmonic mappings in dimension two, certain pairs elliptic partial differential equations with measurable coefficients. Second, apply these results prove new area formulas which are valid for a large class arising solutions equations. Finally, briefly discuss applications homogenized constants context G-closure problems. To Professor Olga A. Ladyzhenskaya our deep admiration
