We consider a multidimensional semilinear reaction-diffusion equation and we obtain at any arbitrary time an approximate controllability result between nonnegative states using as control term the reaction coefficient, that is, via multiplicative controls.

Keywords: Multidimensional semilinear reaction-diffusion equations, approximate controllability, multiplicative controls, nonnegative states.
