摘　　要：拟线性椭圆方程问题是数学学科中重要的研究内容之一。椭圆型微分方程解的存在性问题近年来得到人们的广泛关注,基于文献研究,本文研究一类拟线性椭圆方程边值问题多解的存在性,并验证了一系列引理和定理,运用Nehari流形和纤维映射方法证明了该问题至少有两个正解。The problem of quasilinear elliptic equation is one of the important research contents in mathematics. The existence of solutions for elliptic differential equations has attracted extensive attention in recent years. Based on literature research, this paper studies the existence of multiple solutions for a class of quasilinear elliptic equation boundary value problems, verifies a series of lemmas and theorems, and proves that the problem has at least two positive solutions by using Nehari manifold and fiber mapping method.
