一类p-Kirchhoff方程基态解的存在性与唯一性

对于下面p-Kirchhoff型泛函■我们证明了约束在流形■上全局极小点或山路型临界点的存在性与唯一性,且这些临界点是某个Gagliardo-Nirenberg不等式的最优化子,特别当p∈(1,2]时,它们在不计平移意义下是唯一的.我们扩展了已有文献中p=2的情形的相关结果.     

拟相对论薛定谔方程基态解的存在性与爆破行为

针对如下约束极小化问题da(q)=inf Eq(u),(0,1){u∈H1/2(R3),fR3 |u|2dx=1)其中Eq(u)为拟相对论薛定谔方程的能量泛函Eg(u)=1/2∫R3ū(√-△+m2-m)udx-a/q+2∫R3|u|q+2dx.对任意q∈(0,2/3),该文证明了问题(0.1)至少存在一个径向对称的非...     

EXISTENCE AND STABILITY OF STANDING WAVES FOR A COUPLED NONLINEAR SCHRDINGER SYSTEM

We study the existence and stability of the standing waves of two coupled Schrdinger equations with potentials |x|bi(bi ∈ R, i = 1, 2). Under suitable conditions on the growth of the nonlinear terms, we first establish the existence of standing waves of the Schrdinger system by solving a L2-normalized minimization problem, then prove that the set of all minimizers of this minimization problem is stable. Finally, we obtain the least energy solutions by the Nehari method and prove that the orbit sets of these least energy solutions are unstable, which generalizes the results of [11] where b1= b2= 2.
