Abstract:
In this note we extend weak-type estimates obtained recently by A. K. Lerner to certain grand square functions by using a simple argument in terms of real variables. In this way, we improve a weak-type $L^1$-estimate for grand Littlewood–Paley operators due to N. N. Osipov.
Keywords:
Littlewood–Paley operators, (grand) square functions, sharp aperture dependence, weak-type estimates, Lorentz spaces.
