Abstract
We consider the blow-up solutions to the following coupled nonlinear Schrödinger equations
On the basis of the conservation of mass and energy, we establish two sufficient conditions to obtain the existence of a blow-up for radially symmetric solutions. These results improve the blow-up result of Li and Wu [10] by dropping the hypothesis of finite variance ((∣x∣u0, ∣x∣v0) ∈ L2(ℝN) × L2(ℝN)).
