论文摘要
让我们考虑使用在气候科学中应用的非线性退化反应扩散方程。在任何时间表明该溶液在非负值时仍然是非负数之后，我们在任何时候通过乘法控件（即用作控制反应系数）证明了非负状态之间的近似可控性。
Let us consider a nonlinear degenerate reaction-diffusion equation with application to climate science. After proving that the solution remains nonnegative at any time, when the initial state is nonnegative, we prove the approximate controllability between nonnegative states at any time via multiplicative controls, that is, using as control the reaction coefficient.
