摘要: 考虑一类耦合含梯度项的退化抛物方程组的近似可控性. 当控制函数只作用在一个方程上时, 利用对偶方程组的唯一延拓性证明该方程组的近似可控性.

Abstract: The author considered the approximate controllability of a class of coupled degenerate parabolic equations with the gradient terms. When the control function only acted on one equation, the author proved the approximate controllability of the equation by using the unique continuation of the adjoint equations.

Key words: degenerate parabolic equation, approximate controllability, coupled equation
