Fund Project: Dedicated to the 70th birthday of Professor E. N. Dancer. Research supported by NSFC(11771428, 11871129, 11601353, 11325107) and Beijing Natural Science Foundation(1174013).

In this paper, we consider the following coupled elliptic system

$ \begin{equation} \left\{ \begin{array}{ll} -\Delta u+\lambda_1 u = \mu_1 u^3+\beta uv^2-\gamma v &\text{in } \mathbb{R}^N, \\ -\Delta v+\lambda_2 v = \mu_2 v^3+\beta vu^2-\gamma u &\text{in } \mathbb{R}^N, \\ u(x), v(x)\rightarrow 0 \text{ as } \vert x\vert\rightarrow+\infty. \end{array} \right.\nonumber \end{equation} $

Under symmetric assumptions

$ \lambda_1 = \lambda_2, \mu_1 = \mu_2 $

, we determine the number of

$ \gamma $

-bifurcations for each

$ \beta\in(-1, +\infty) $

, and study the behavior of global

$ \gamma $

-bifurcation branches in

$ [-1, 0]\times H_r^1\left( \mathbb{R} ^N\right)\times H_r^1\left( \mathbb{R} ^N\right) $

. Moreover, several results for

$ \gamma = 0 $

, such as priori bounds, are of independent interests, which are improvements of corresponding theorems in [6] and [35].

Keywords: Bifurcation, Schrödinger systems, positive solutions.
