We consider the Hénon-type quasilinear elliptic equation \({-\Delta_m u=|x|^a u^p}\) where \({\Delta_m u={\rm div}(|\nabla u|^{m-2} \nabla u)}\), m > 1, p > m ?1 and \({a\geq 0}\). We are concerned with the Liouville property, i.e. the nonexistence of positive solutions in the whole space \({{\mathbb R}^N}\). We prove the optimal Liouville-type theorem for dimension N < m + 1 and give partial results for higher dimensions. Keywords Quasilinear Liouville-type theorem Hénon-typeequation
