Abstract

Let Φ(t)= ∫_0^t a(s) ds and Ψ(t)= ∫_0^t b(s) ds, where a(s) is a positive continuous function such that ∫_0^1 frac{a(s)}{s} ds < ∞and ∫_1^{∞}frac{a(s)}{s} ds= +∞, and b(s) is an increasing function such that lim_{sto∞}b(s)= +∞. Letw be a weight function and suppose that w∈A1∩ A'. Then the following statements for the Hardy-Littlewood maximal function Mf(x) are equivalent:(I) there exist positive constants C 1 and C 2 such that 0;$$ ]]> (II) there exist positive constants C 3 and C 4 such that
