摘要: 该文讨论了R2中一类带不定权且含临界位势的二阶椭圆方程的特征值问题,然后,借此特征值问题的第一特征值性质,利用临界点理论及Trudinger-Moser不等式,证明了R2 中一类带不定权且含临界位势的二阶非线性椭圆方程非平凡解的存在性.

关键词: 特征值问题, 不定权, 临界点理论

Abstract: The eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is investigated. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, the authors prove the existence of nontrivial solutions for a class of nonlinear elliptic equations with critical potential and indefinite weights in R2.

Key words: Eigenvalue problem, Indefinite weights, Critical point theory
