摘要
We consider the Cauchy problem for a higher order pseudo-hyperbolic equation. Using the L-p -> L-q type estimation for the corresponding linear problem, the existence and nonexistence criteria of global solutions are found. The existence and uniqueness of smooth global solutions are also investigated. We also establish the behavior of solutions and their derivatives as t -> +infinity. (C) 2009 Elsevier Ltd.
