Let ? be full Laplacian on H-type group G. Then for every compact set D ■ G,a local estimate of the Schr¨odinger maximal operator holds, that is, ∫_(D)su
In this article, we study the following nonhomogeneous Schr¨odinger-Poisson equations -?u + λV(x)u + K(x)φu = f(x, u) + g(x), x ∈ R~3,?-?φ = K(x)u~2, x
