Heat maximal function on a Lie group of exponential growth
Artikel i vetenskaplig tidskrift, 2012

Let G be the Lie group R2 x R+ (semidirect product) endowed with the Riemannian symmetric space structure. Let X0; X1; X2 be a distinguished basis of left-invariant vector fields of the Lie algebra of G and write L for the corresponding Laplacian. In this paper, we show that the maximal function associated with the heat kernel of L is bounded from the Hardy space H1 to L1. We also prove that the heat maximal function does not provide a maximal characterization of the Hardy space H1
