Dr. Igor Verbitsky’ s research focuses on harmonic analysis and nonlinear potential theory methods, and their applications to linear, quasilinear, and fully nonlinear equations with singular coefficients and data.
He studies weighted norm inequalities, existence, uniqueness, and regularity properties, global and local estimates of solutions, singularities and exceptional sets. His work has been published in Annals of Mathematics, Acta Mathematica, Inventiones Mathematicae, Communications on Pure and Applied Mathematics, Archive for Rational Mechanics and Analysis, Advances in Mathematics, Journal of Functional Analysis, Journal d'Analyse Mathematique, Journal fur die reine und angewandte Mathematik (Crelle's Journal), etc.
