Riemann-Stieltjes operators on some general spaces on the unit ball and their essential norm

Abstract

The objective of this paper is to find an estimation of the essential norm of Riemann-Stieltjes operator from the spaces $F(p,q,s)$ ( general function space) and $H(p,q,\varphi )$ (mixed-norm space) into Zygmund-type space in the unit ball of ${\mathbb{C}}^n$.
