报告摘要：
For the spherical average A and the Laplace operator Δ, in this talk we will introduce the iterated operator Δ(A)^{N} and find the minimal positive integer N to ensure the L¹(??) boundedness of
Δ(A)^{N}. Using a constructive proof, we completely solve a question posted by Belinsky, Dai and Ditzian posed in 2003.
