混合色散非线性薛定谔方程在质量临界和超临界区域的归一化解

Denis Bonheure, Jean-Baptiste Casteras, Tianxiang Gou, Louis Jeanjean

摘要:

本文研究了混合色散非线性薛定谔方程$$ γΔ^2 u -Δu + αu=|u|^{2 σ} u, \quad u \in H^2(\R^N), $$在约束$$ \int_{\R^N}|u|^2 \, dx =c>0. $$下解的存在性。我们假设$γ>0, N \geq 1, 4 \leq σN < \frac{4N}{(N-4)^+}$,而参数$α\in \R$将以Lagrange乘子的形式出现。在给定$c \in \R^+$的条件下,我们考虑了基态、正解和径向解的多重性等问题。我们还讨论了相应色散方程驻波的稳定性。

英文摘要:

In this paper, we study the existence of solutions to the mixed dispersion nonlinear Schrödinger equation $$ γΔ^2 u -Δu + αu=|u|^{2 σ} u, \quad u \in H^2(\R^N), $$ under the constraint $$ \int_{\R^N}|u|^2 \, dx =c>0. $$ We assume $γ>0, N \geq 1, 4 \leq σN < \frac{4N}{(N-4)^+}$, whereas the parameter $α\in \R$ will appear as a Lagrange multiplier. Given $c \in \R^+$, we consider several questions including the existence of ground states, of positive solutions and the multiplicity of radial solutions. We also discuss the stability of the standing waves of the associated dispersive equation.
