报告摘要: In this talk, we concern with the constrained minimization problem of a Kirchhoff-Schrödinger energy functional under an L²-subcritical subcritical perturbation. The existence and nonexistence of constraint minimizers are completely classified in terms of the L²- subcritical exponent. Especially for q∈(4/3, 8/3), we prove that there exists a critical value β* such that minimization problem has no minimizer if the coefficient β of L²-critical term satisfies β=β*. For q∈(4/3, 8/3), the blow-up behavior of minimizers as β→β* are also analyzed rigorously if the coefficient λ of L²-subcritical term satisfies λ>λ₀, where λ₀  is a positive constant.
