%0 Journal Article %T An iteration method for controllability of semilinear parabolic equations %A Bo Sun %J Electronic Journal of Differential Equations %D 2010 %I Texas State University %X We present a method based on Picard's idea to construct a sequence of controls and a sequence of solutions of linearized systems such that their limits form a solution to the control problem. By doing this, we simplified the works in the references, and deduced the controllability for semilinear coupled parabolic systems. %K Semilinear %K parabolic equation %K controllability %K iteration method %K coupled systems %U http://ejde.math.txstate.edu/Volumes/2010/148/abstr.html
