Une équation parabolique p-laplacienne avec un terme source non linéaire général est considérée. On montre que la solution peut exploser en temps fini pour une énergie initiale positive. De plus, sous certaines hypothèses appropriées concernant le terme source non linéaire, il est prouvé que la solution explose en temps fini pour une énergie initiale arbitrairement élevée. Ces résultats généralisent des résultats antérieurs.

A p-Laplacian parabolic equation with a general nonlinear source term is considered. It is shown that the solution may blow up in finite time at positive initial energy. Moreover, under some suitable assumptions about the nonlinear source term, the solution is proved to blow up in finite time at arbitrarily high initial energy. These results generalize the previous ones.
