Abstract
In this paper, we discuss the controllability of a nonlinear degenerate parabolic system with bilinear
control. Based on the shrinking property of the solutions, we prove that the system is not globally approximately
controllable. Furthermore, we give an approximate null controllability result.We also prove that the
system is not globally exactly null controllable by a comparison principle.
