Abstract

In this paper, we study the nonlinearly coupled Schrödinger equations for atomic Bose–Einstein condensates. By the Galërkin method and a priori estimates, the global existence of a smooth solution is obtained. Under some assumptions of the coefficients and $p$, the blow-up theorem is established.
