Descripción
Sumario:The aim of this work is to consider bicomplex Bernstein polynomials attached to analytic functions on a compact <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi mathvariant="double-struck">C</mi><mn>2</mn></msub></semantics></math></inline-formula>-disk and to present some approximation properties extending known approximation results for the complex Bernstein polynomials. Furthermore, we obtain and present quantitative estimate inequalities and the Voronovskaja-type result for analytic functions by bicomplex Bernstein polynomials.
