In this paper, we prove the existence of non-radial solutions to the problem u=f(z,u), u|D=0 on the unit disc D{z:|z|<1} with u(z)Rk, where f is a sub-linear continuous function, differentiable with respect to u at zero and satisfying f(eiθz,u)=f(z,u) for all θR, f(z,u)=f(z,u). Under the assumption that f respects additional (spacial) symmetries on Rk, we investigate symmetric properties of the corresponding non-radial solutions. The abstract result is supported by a numerical example with S4-symmetry.

圆盘上耦合半线性椭圆系统的非径向解的模式

在本文中,我们证明了该问题的非径向解的存在 -ü=Fžüü|d=0 在单元光盘上 d{ž|ž|<1个}üž[Rķ,在哪里 F 是一个亚线性连续函数,相对于 ü 零且令人满意 FË一世θžü=Fžü 对所有人 θ[RFž-ü=-Fžü。假设F 尊重上的其他(空间)对称性 [Rķ,我们研究了相应的非径向解的对称性质。一个数字示例支持抽象结果小号4-对称。
