本文给出了一个简单的证明,证明了一类Kirchhoff型方程对$N$,对$N$,至少存在一个非平凡解。特别地,在本文的第一部分,我们感兴趣地研究了在满足一般的Berestycki-Lions假设的非线性项的作用下,椭圆型Kirchhoff方程正解的存在性。在第二部分中,我们使用适当的自然约束的最小化论点来寻找基态。
In this paper we present a very simple proof of the existence of at least one non trivial solution for a Kirchhoff type equation on $\RN$, for $N\ge 3$. In particular, in the first part of the paper we are interested in studying the existence of a positive solution to the elliptic Kirchhoff equation under the effect of a nonlinearity satisfying the general Berestycki-Lions assumptions. In the second part we look for ground states using minimizing arguments on a suitable natural constraint.
