New weighted multilinear operators and commutators of Hardy-Cesàro type

Ha Duy Hung, Luong Dang Ky

A general class of weighted multilinear Hardy-Cesàro operators that acts on the product of Lebesgue spaces and central Morrey spaces. Their sharp bounds are also obtained. In addit…

An Hardy estimate for commutators of pseudo-differential operators

Ha Duy Hung, Luong Dang Ky

Let $T$ be a pseudo-differential operator whose symbol belongs to the Hörmander class $S_{ρ, δ}^{m}$ with $0 \leq δ < 1, 0 < ρ \leq 1, δ \leq ρ$ and $- (n + 1) < m \leq - (n + 1) (1 - ρ)$ . In presen…
