Necessary and sufficient conditions for the two-weight weak type maximal inequality in Orlicz class Yanbo Ren; Shuang Ding — 2022 Czechoslovak Mathematical Journal We collect known and prove new necessary and sufficient conditions for the weighted weak type maximal inequality of the form Φ 1 ( λ ) ϱ ( { x ∈ X : M μ f ( x ) > λ } ) ≤ c ∫ X Φ 2 ( c | f ( x ) | ) σ ( x ) d μ ( x ) , which extends some known results.
