本文针对三维定常热带气候模型，在不施加任何温度假设的前提下，建立了两个改进型Liouville型定理。利用方程固有的特殊结构，充分挖掘了温度振荡的L²估计、改进的插值技术以及迭代论证，在更灵活宽松的幂律增长条件下建立了一个Liouville型定理。作为一个有趣的推论，在仅对(u,∇v)或(∇u,∇v)施加可积性条件时，我们得到了解的平凡性。此外，通过开发处理非平凡解相关能量函数的系统框架，并借助精细的常微分方程分析和反证法，我们通过对增长率引入对数修正，改进了Liouville型定理。
英文摘要
In this paper, we establish two improved Liouville-type theorems for the three-dimensional stationary tropical climate model without imposing any temperature assumptions. Owing to the special structure inherent to the equations, we fully exploit the $L^2$-estimate for the oscillation of the temperature, refined interpolation techniques and an iteration argument to establish a Liouville-type theorem under more flexible and relaxed power-law growth conditions. As an interesting consequence, we obtain the triviality of solutions under the integrability conditions imposed only on $(u,\nabla v)$ or $(\nabla u,\nabla v)$. Furthermore, by developing a systematic framework to handle the energy function associated with the non-trivial solutions and with the aid of delicate ODE analysis and a contradiction argument, we refine our Liouville-type theorem by introducing logarithmic corrections to the growth rates.
