摘要: 对二阶非线性椭圆型方程
i,j=1n Di[Aij(x)Djy]+∑i=1n bi(x)Diy+q(x)f(y)=e(x)
建立了若干新的振动准则, 所得结果仅依赖于方程在外区域Ω С Rn的一个子区域序列的信息而有别于已知的大多数结论.

关键词: 二阶非线性椭圆型方程, 强迫项, 振动性, 区域准则

Abstract: In this paper, new oscillation criteria are obtained for nonlinear elliptic differential equations of the form
i,j=1n Di[Aij(x)Djy]+∑i=1n bi(x)Diy+q(x)f(y)=e(x)
where x∈ Rn. These criteria are only based on the information of a sequence of subdomain of Ω С Rnand different from most known ones.

Key words: Second order nonlinear elliptic equation, Forcing term, Oscillation, Domain criteria
