摘要
The author considers the global existence and global nonexistence of theinitial-boundary value problem for some degenerate hyperbolic equation of the formutt ? div(|?u|p?2?u) = |u|mu, (x, t) ∈ [0, +∞) × ?with p > 2 and m > 0. He deals with the global solutions by D.H.Sattinger’s potential wellideas. At the same time, when the initial energy is positive, but appropriately bounded,the global nonexistence of solutions is verified by using the analysis method.
