摘要

Let L := -Delta + V be a Schrodinger operator with the nonnegative potential V belonging to the reverse Holder class RHq0(R-n) for some q(0) is an element of [n, infinity) with n >= 3, and phi : R-n x [0, infinity) -> [0, infinity) a function such that phi(x, .) is an Orlicz function, phi(., t) is an element of A(infinity)(R-n) (the class of uniformly Muckenhoupt weights) and its uniformly critical lower type index i(phi) is an element of (n+1, 1]. In this article, the authors prove that the second order Riesz transform del L-2(-1) associated with L is bounded from the Musielak-Orlicz-Hardy space associated with L, H-phi, L(R-n), to the Musielak-Orlicz-Hardy space H-phi(R-n), via establishing an atomic characterization of H-phi, L(R-n). As an application, the authors prove that the operator V L-1 is bounded on the Musielak-Orlicz-Hardy space H-phi, L(R-n), which further gives the maximal inequality associated with L in H-phi, L(R-n). All these results are new even when phi(x, t) := t(p), with p is an element of (n+1 n, 1], for all x is an element of R-n and t is an element of [0, infinity).
