### Field of research

Constructive function theory in several variables (Bernstein, Jackson and Markov type polynomial inequalities
on subsets of R^{N} and C^{N}, pluripotential theory, polynomial approximation, continuation of smooth function
defined on compact subsets of R^{N}) and theory of minimal projections in Banach spaces (problems of the existence
and uniqueness, formulas for minimal projections, estimates of absolute projection
constant).
