摘要
利用Ekeland's变分原理和山路引理,获得一类具有凹凸非线性项和变号位势的椭圆系统至少2个非平凡非负解的存在性.
According to the Ekeland's variational principle and the mountain pass theorem,the existence of at least two nontrivial solutions for a class of quasilinear elliptic systems involving concave-convex nonlinearities and sign-changing weight functions has been obtained.
