Abstract:

This paper is concerned with the initial boundary value problem of non-Newtonian filtration equations at critical initial energy level. We first construct a new potential well and its outside set, and prove their invariance. Furthermore, the global existence and finite time blow-up of solutions are obtained.

Key words: Non-Newtonian filtration equations, Global existence, Finite time blow-up, Potential well, Critical initial energy
