摘要：
Motivated by the possible singularity of stationary state, we revisit the initial boundary value problem of the classical Klein-Gordon-Schrodinger (KGS) system in one space dimension. Our result shows there exist singular solutions, part of which may increase exponentially with respect to the spatial variable. (c) 2022 Elsevier Ltd. All rights reserved.
