In this paper, we study a class of semilinear -Laplacian equations with variable exponent sources. By using potential well method, we first prove a threshold results on the existence and nonexistence of global solutions to the equations when initial energy is less than the mountain pass level . In the former case we also show the decay properties of energy functional. We finally obtain the non-global existence results with high energy initial data.

势阱法 -具有可变指数源的拉普拉斯方程
在本文中,我们研究了一类半线性 -具有可变指数源的拉普拉斯方程。通过使用势阱方法,我们首先证明了当初始能量小于山口通过水平时,方程整体解的存在与否的阈值结果。在前一种情况下,我们还显示了能量函数的衰减特性。我们最终获得了具有高能量初始数据的非全局存在结果。
