摘要

我们考虑了一个由双相微分算子和反应驱动的非线性迪里夏特问题，该反应具有参数凹项和对流扰动的竞争效应。利用截断和比较技术以及单调型非线性算子理论，我们证明了对于所有小的参数值，该问题都有一个有界的正解。

Positive Solutions for Convective Double Phase Problems

We consider a nonlinear Dirichlet problem driven by the double phase differential operator and a reaction that has the competing effects of a parametric concave term and of a convective perturbation. Using truncation and comparison techniques and the theory of nonlinear operators of monotone type, we show that for all small values of the parameter, the problem has a bounded positive solution.
