摘要 本文利用Brezia-Nirenberg型山路引理研究了包括Extended Fisher-Kolmogorov方程和Swift-Hohenberg方程在内的一类四阶微分方程的同宿轨道解存在性.利用同样的方法,也研究了具有一般的超二次位势函数的四阶微分方程u(iv)+pu″+a(x)u-Vu(x,u)=0的同宿轨道解. In this paper we study the existence of homoclinic solutions of Fisher-Kolmogorov equation and Swift Hohenberg equation. We study also the homoclinic solutions for the fourth-order equation u^(w)+pu''+a(x)u-Vu(x,u)=0, where a ( x ) is a periodic function and V( x, u) satisfies Ambrosetti and Rabinowitz type superquadratic condition. The Mountain-Pass Theorem of Brezis are used.
