Course Language English N/A Natural & Applied Sciences Master's Degree Face To Face Lecture, Question and Answer, Problem Solving. Prof. Dr. Sofiya Ostrovska This graduate level course is designed to provide math students with the knowledge of basic facts about the Bernstein polynomials and their role in analysis and approximation theory, as well as demonstrate their applications and generalizations. For this purpose, the course includes topics on positive linear operators, Kantorovich polynomials, and the De Casteljau algorithm, which are closely related to the Bernstein polynomials. The students who succeeded in this course; understand the notions of uniform continuity and uniform approximation; construct the Bernstein, Chlodovsky and Kantorovich polynomials of functions given on different intervals; apply Korovkin’s theorem to establish the approximation by a sequence of positive linear operators; use the Bernstein polynomials in applied problems; understand shape-preserving and degree-reducing properties of the Bernstein polynomials. Uniform continuity, uniform convergence, Bernstein polynomials, Weierstrass approximation theorem, positive linear operators, Popoviciu theorem, Voronovskaya theorem, simultaneous approximation, shape-preserving properties, De Casteljau algorithm, complex Bernstein polynomials, Kantorovich polynomials.
