Kolkovska, Natalia

My scientific interests are in the field of numerical methods for solving differential and integral equations, in particular - the methods of finite differences, finite elements, boundary elements, as well as their application to the mathematical models of physical and industrial processes.

My mathematical work is primary connected with the approximation theory. Other areas of interest are varying fields of analysis, analytic number theory, numerical methods and mathematical modeling. I am also interested in the theory and application of the electoral systems, election conduct and observation.

Draganov, Borislav

I carry out research mostly in the field of approximation theory. In the recent years I have been particularly interested in establishing a precise and useful characterization of the rate of convergence of various approximation processes generated either by linear operators or by non-linear as best (weighted) approximation by algebraic or trigonometric polynomials. My research also includes interpolation, (generalized) Fourier expansions, orthogonal polynomials, quadrature formulae, multipliers, application of Fourier analysis in approximation theory, and functional analysis.
