Classes of weights related to Schrodinger operators

In this work we obtain boundedness on weighted Lebesgue spaces on R-d of the semi-group maximal function, Riesz transforms, fractional integrals and g-function associated to the Schrodinger operator -Delta + V. where V satisfies a reverse Holder inequality with exponent greater than d/2. We consider new classes of weights that locally behave as Muckenhoupt's weights and actually include them. The notion of locality is defined by means of the critical radius function of the potential V given in Shen (1995) [8]. (C) 2010 Elsevier Inc. All rights reserved.
