On the interference of the weight and boundary contour for algebraic polynomials in weighted Lebesgue spaces. II

We continue to study the estimation of the modulus of algebraic polynomials on the boundary contour with weight function, when the contour and the weight function have certain singularities with respect to the their quasinorm in the weighted Lebesgue space. In particular, the exact estimates were ob...

description We continue to study the estimation of the modulus of algebraic polynomials on the boundary contour with weight function, when the contour and the weight function have certain singularities with respect to the their quasinorm in the weighted Lebesgue space. In particular, the exact estimates were obtained for polynomials orthonormal on the curve with respect to the weight function with zeros on the same curve.

Ми продовжуємо дослiдження модулiв алгебраїчних полiномiв на граничному контурi з ваговою функцiєю у випадку, коли цей контур та вагова функцiя мають деякi сингулярностi вiдносно їх квазiнорми у ваговому просторi Лебега. Зокрема, точнi оцiнки було отримано для полiномiв, ортонормальних на кривiй вiдносно вагової функцiї з нулями на цiй кривiй.
