DOI: 10.1016/j.jmaa.2017.10.048
Abstract: Abstract We show existence theorem of global mild solutions with small initial data and external forces in Lorentz spaces with scaling invariant norms. If the initial data have more regularity in another scaling invariant class,… read more here.

DOI: 10.1016/j.jmaa.2018.11.076
Abstract: Abstract By means of the technique of Burkholder's martingale transforms, the interchanging relations between “predictable” martingale Hardy–Lorentz spaces are characterized. More precisely, let 0 p 1 p 2 ∞ and 0 q 1 ≤ q… read more here.
