Maximal operators, Lebesgue points and quasicontinuity in strongly nonlinear
potential theory
N. Aissaoui
Abstract.
Many maximal functions defined on some Orlicz spaces $\mathbf L _ A $ are bounded operators on $\mathbf L _ A $ if and only if they satisfy a capacitary weak inequality. We show also that $(m,A)-$quasievery $x$ is a Lebesgue point for $f$ in $\mathbf L _ A $ sense and we give an $(m,A)-$ quasicontinuous representative for $f$ when $L_A$ is reflexive.
