We show the uniqueness of the very singular self-similar solution of the equation ut - Δ pum + uq = 0. The result is carried out by studying the stationary associate equation and by introducing a suitable change of unknown. That allows to assume the zero-order perturbation term in the new equation to be monotone increasing. A careful study of the behaviour...
