英文摘要We study the Schrodinger systems with linear and nonlinear coupling terms (doubly coupled nonlinear Schrodinger system for short) which arise naturally in nonlinear optics, and in the Hartree-Fock theory for Bose-Einstein condensates, among other physical problems. First, for small linear coupling constant, we get existence of a nontrivial bound state solution to the system via perturbation method, furthermore, we prove each component of the bound state solution is nonnegative by energy estimate. Second, we establish a version of Pohozaev-Nehari identity and prove a nonexistence result for the more general system when the spatial dimension N >= 4. (C) 2019 Elsevier Inc. All rights reserved.
