Higher integrability for the solution to a class of Schrodinger euqations

In this article,a class of Schrodinger euqations is considered.Under the assumptions that potential V satisfying an appropriate reverse Hlder condition and the coefficients are belong to VMO class,a Lp higher integrability result for Schrodinger euqations is obtained by using bootstrapping techniques and then the classic Lp regularity result for elliptic equations is extended to the case of Schrodinger euqations.
