Dong, Jian Feng et Liu, He Ping, The BMO L space and Riesz transforms associated with Schrödinger operators, Acta mathematica Sinica. English series (Print) , 26(4), 2010, pp. 659-668
Let L = .. + V be a Schrödinger operator in .d, d . 3, where the nonnegative potential V belongs to the reverse Hölder class B d . We establish the BMO L -boundedness of Riesz transforms ..xiL.12, and give the Fefferman-Stein type decomposition of BMO L functions
