摘要:
我们研究 $\mathbb{R}^{4}$ 单位球中的一个加权双调和问题。根据 Adam 型不等式,假设非线性项具有临界指数增长。权重 $w(x)$ 为对数型,势函数 $V$ 是 $\overline{B}$ 上的正连续函数。通过山路定理证明了该问题存在一个非平凡正弱解。我们通过证明一个集中紧性结果并借助适当的渐近条件,避免了紧性的丧失。
英文摘要:
We deal with a weighted biharmonic problem in the unit ball of $\mathbb{R}^{4}$. The non-linearity is assumed to have critical exponential growth in view of Adam's type inequalities. The weight $w(x)$ is of logarithm type and the potential $V$ is a positive continuous function on $\overline{B}$. It is proved that there is a nontrivial positive weak solution to this problem by the mountain Pass Theorem. We avoid the loss of compactness by proving a concentration compactness result and by a suitable asymptotic condition.
