RT Journal Article T1 On the approximate controllability of some semilinear parabolic boundary-value problems A1 Díaz Díaz, Jesús Ildefonso A1 Henry, J. A1 Ramos Del Olmo, Ángel Manuel AB We prove the approximate controllability of several nonlinear parabolic boundary-value problems by means of two different methods: the first one can be called a Cancellation method and the second one uses the Kakutani fixed-point theorem.
