摘要

This paper concerns the approximate controllability of the initial-boundary problem of double coupled semilinear degenerate parabolic equa-tions. The equations are degenerate at the boundary, and the control function acts in the interior of the spacial domain and acts only on one equation. We overcome the difficulty of the degeneracy of the equations to show that the problem is approximately controllable in L2 by means of a fixed point theorem and some compact estimates. That is to say, for any initial and desired data in L2, one can find a control function in L2 such that the weak solution to the problem approximately reaches the desired data in L2 at the terminal time.
