令L=-△+V是欧氏空间R^d上具有非负多项式位势的薛定谔算子.BMOL(R^d)是与薛定谔算子相关的哈代型空间H^1L±(R^d)的对偶空间.该文证明当位势V是非负多项式时,薛定谔型算子(-△+V)-β 是从L^P(R^d)到BMOL(R^d)的有界线性算子,其中P=d/2β-1.
Abstract: Let L = -△+V be the SchrSdinger operator on R^d with the potential V being a nonnegative polynomial. BMOL (R^d) is a dual space of the Hardy-type space H^1L (R^d) related to Schrodinger operator L =-△+V. In this article it is proved that the SchrSdinger type operator (-△+V)-β is bounded from LP(R^d) into BMOL(R^d) for p = d/2β-1 when the potential V is a nonnegative polynomial.
