Ángel Crespo-Blanco, Patrick Winkert

AI总结:

针对变指数双相位算子驱动的超线性拟线性椭圆方程,论文采用 Nehari 流形方法证明正解、负解及变号解的存在性,并刻画变号解的节点域。

摘要:

本文研究由变指数双相位算子驱动、右端项具有超线性性质的拟线性椭圆方程。在对非线性性作非常一般假设的条件下,我们证明了此类问题的多重性结果:存在一个正解、一个负解以及一个变号解。变号解通过 Nehari 流形方法获得,此外,我们还能给出关于其节点域的信息。

英文摘要:

In this paper we consider quasilinear elliptic equations driven by the variable exponent double phase operator with superlinear right-hand sides. Under very general assumptions on the nonlinearity, we prove a multiplicity result for such problems whereby we show the existence of a positive solution, a negative one and a solution with changing sign. The sign-changing solution is obtained via the Nehari manifold approach and, in addition, we can also give information on its nodal domains.
