Generalized Jacobi-Weierstrass operators and Jacobi expansions.

J Inequal Appl 2018 28;2018(1):153. Epub 2018 Jun 28.

We present a realization for some -functionals associated with Jacobi expansions in terms of generalized Jacobi-Weierstrass operators. Fractional powers of the operators as well as results concerning simultaneous approximation and Nikolskii-Stechkin type inequalities are also considered.
