Norm of the Hausdorff operator on the real Hardy space $H^{1} (R)$

Ha Duy Hung, Luong Dang Ky, Thai Thuan Quang

Let $φ$ be a nonnegative integrable function on $(0, \infty)$ . It is well-known that the Hausdorff operator $H_{φ}$ generated by $φ$ is bounded on the real Hardy space $H^1(\…

On the product of functions in $B M O$ and $H^{1}$ over spaces of homogeneous type

Luong Dang Ky

Let $X$ be an RD-space, which means that $X$ is a space of homogeneous type in the sense of Coifman-Weiss with the additional property that a reverse doubling pro…

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…

On weak $^{*}$ -convergence in $H_{L}^{1} (R^{d})$

Luong Dang Ky

Let $L = - Δ + V$ be a Schrödinger operator on $R^{d}$ , $d \geq 3$ , where $V$ is a nonnegative function, $V \neq = 0$ , and belongs to the reverse Hölder class $R H_{d /2}$ . In this pap…
