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
