A dimension-free estimate for the semi-commutative discrete spherical maximal operator

  • Yue Zhang

摘要

In this paper, we establish a dimension-free estimate for the semi-commutative discrete spherical maximal operator on \(L_{p}\) L p spaces for \(2\le p\le \infty \) 2 p . This result extends the work of Mirek, Szarek, and Wróbel (Int. Math. Res. Not. no.2:901–963, 2024) to the operator-valued setting.
