摘要

在本文中，我们考虑了带有非线性阻尼和源项的加权双谐波方程。我们证明了解的全局存在性。随后，利用中尾不等式确定了能量的衰减。最后，我们证明了有限时间内解的炸毁。

Existence, Decay, and Blow-up of Solutions for a Weighted -Biharmonic Equation with Nonlinear Damping and Source Terms

In this paper, we consider the weighted -biharmonic equation with nonlinear damping and source terms. We proved the global existence of solutions. Later, the decay of the energy is established by using Nakao’s inequality. Finally, we proved the blow-up of solutions in finite time.
