Nehari流形上具有非线性边界条件的双相问题的变号解

Sign changing solution for a double phase problem with nonlinear boundary condition via the Nehari manifold

Leszek Gasinski, Patrick Winkert

摘要:

本文研究了由双相算子驱动的具有非线性边界条件的拟线性椭圆型方程。由于缺乏规律性,我们证明了多重解的存在性,应用Nehari流形方法,截断和比较技术和临界点理论。此外,我们还可以确定解的符号(一个正,一个负,一个节点)。此外,作为独立兴趣的结果,我们证明了这类问题的弱解的有界性。

英文摘要:

In this paper we study quasilinear elliptic equations driven by the so-called double phase operator and with a nonlinear boundary condition. Due to the lack of regularity, we prove the existence of multiple solutions by applying the Nehari manifold method along with truncation and comparison techniques and critical point theory. In addition, we can also determine the sign of the solutions (one positive, one negative, one nodal). Moreover, as a result of independent interest, we prove for a general class of such problems the boundedness of weak solutions.
