Exact controllability of the radial solutions of the semilinear wave equation in R3

By Luz de Teresa


The exact internal controllability of the radial solutions of a semilinear heat equation in IR3 is proved. The result applies for nonlinearities that are of an order smaller than | s | logp | s | at infinity for 1 £ p<2. The method of the proof combines HUM and a fixed point technique
