Abstract:
To generalize H-L maximal function to vector-valued weighted space, it is proved that for a weighted function υ(x)≥0, the necessary and sufficient conditions are obtained for ∫
Rnυ(x)(1+(|x|
n)
-pdx<)∞, such that the vector-valued H-L maximal operator is bounded from L

q(R
n, ωdx) to L
p(R
n, υdx) for some ω(x) that is related to υ(x) and ω(x)<∞, a.e.x∈R
n.Based on the double property, Hlder's inequality et al, the sufficiency condition of the theorem are proved.Employing the eigenfunction, the vector-valued functions are set up, and conditions of necessity of the theorem are completed.
