Abstract
A nonexistence result is proved of the space higher-order nonlinear Schrödinger equation (equation presented) where m > 1, n > 1 and p > n. Our method of proof rests on a judicious choice of the test function in the weak formulation of the equation. Then, we obtain an upper bound of the life span of solutions. Furthermore, the necessary conditions for the existence of local or global solutions are provided. Next, we extend our results to the 2 × 2 - system (equation presented) where m > 1, p, q > 1, and λ, δ ∈ C\{0}.
