In this talk, Fefferman-Stein inequalities in 𝐿𝑝(ℝ𝑑;ℓ𝑞) with bounds independent of the dimension 𝑑 are proved, for all 1<𝑝,𝑞<+∞. This result generalizes in a vector-valued setting the famous one by Stein for the standard Hardy-Littlewood maximal operator. We then extend our result by replacing ℓ𝑞 with an arbitrary UMD Banach lattice. Finally, we prove similar dimensionless inequalities in the setting of the Grushin operators.
