Non-commutative measure of quantum correlations under local operations
(Springer, 2019-02)
We study some desirable properties of recently introduced measures of quantum correlations based on the amount of non-commutativity quantified by the Hilbert–Schmidt norm (Guo in Sci Rep 6:25241, 2016; Majtey et al. in ...
Musielak-Orlicz-bumps and Bloom type estimates for commutators of Calderón-Zygmund and fractional integral operators on generalized Zygmund spaces via sparse operators
(Akadémiai Kiadó, 2021-04-10)
We study continuity properties for commutators of Calderón-Zygmund and fractional integral operators between generalized Zygmund spaces of L log L type, in the variable exponent setting with different weights. In order to ...
The influence of working from home and underlying attitudes on the number of commuting and non-commuting trips by workers during 2020 and 2021 pre- and post-lockdown in Australia
(2024)
Since the start of 2020, we have seen major changes in the way communities operate. Mobility behaviour has been drastically impacted by work from home (WFH) and by lockdowns and restrictions in different jurisdictions. ...
Mixed weak estimates of Sawyer type for commutators of generalized singular integrals and related operators
(Michigan Mathematical Journal, 2019-09)
We study mixed weak type inequalities for the commutator [b,T], where b is a BMO function and T is a Calderón-Zygmund operator. Our technique involves the classical Calderón–Zygmund decomposition, which allows us to give ...
On pointwise and weighted estimates for commutators of Calderón–Zygmund operators
(Academic Press Inc Elsevier Science, 2017-10)
In recent years, it has been well understood that a Calderón–Zygmund operator T is pointwise controlled by a finite number of dyadic operators of a very simple structure (called the sparse operators). We obtain a similar ...
The Toeplitz algebra on the Bergman space coincides with its commutator ideal
(Theta Foundation, 2004-12)
Let L^2-a be the Bergman space of the unit disk and T(L^2_a) be the Banach algebra generated by Toeplitz operators T_f , with f ∈ L∞. We prove that the closed bilateral ideal of T(L2a) generated by operators of the form ...
Commutators of potential type operators with Lipschitz symbols on variable Lebesgue spaces with different weights
(Element, 2019-07)
We prove that a generalized Fefferman-Phong type condition on a pair of weights uand v is sufficient for the boundedness of the commutators of potential type operators from Lp(·)_v into Lq(·)_u. We also give an improvement ...
Potential operators and their commutators acting between variable Lebesgue spaces with different weights
(Taylor & Francis, 2018-11)
We prove that a generalized Fefferman–Phong type conditions on a pair of weights u and v is sufficient for the boundedness of the potential type operator from Lv p(.) into Lu q(.). We also obtain an analogous estimates for ...
