Essential norm of Riemann–Stieltjes operator on weighted Bergman spaces with doubling weights.

Let ω be a doubling weight and 0 < p ≤ q < ∞ . The essential norm of Riemann–Stieltjes operator T g from the weighted Bergman space A ω p to A ω q was investigated in the unit ball of ℂ n . [ABSTRACT FROM AUTHOR]
