Abstract

Let =-Δ𝔾+V be a Schrödinger operator on the stratified Lie group 𝔾, where Δ𝔾 is the sub-Laplacian and the nonnegative potential V belongs to the reverse Hölder class Bq0 with q0>𝒬/2 and 𝒬 is the homogeneous dimension of 𝔾. In this article, by Campanato type spaces Λα(𝔾), we introduce Hardy type spaces associated with denoted by Hp(𝔾) and prove the atomic characterization of Hp(𝔾). Further, we obtain the following duality relation:

Λ𝒬(1/p-1)(𝔾)=(Hp(𝔾)),𝒬/(𝒬+δ)<p<1forδ=min{1,2-𝒬/q0}.

The above relation enables us to characterize Λα(𝔾) via two families of Carleson measures generated by the heat semigroup and the Poisson semigroup, respectively. Also, we obtain two classes of perturbation formulas associated with the semigroups related to . As applications, we obtain the boundedness of the Littlewood–Paley function and the Lusin area function on Λα(𝔾).
