Abstract: We discuss some recent results on local and global bifurcation structure for a nonlinear system of Schr\"odinger type equations. The results give multiplicity of positive bound state solutions of the system in the repulsive case. The methods involve linear spectrum analysis, Rabinowitz's global bifurcation theorem, and a new Liouville type theorem for nonlinear elliptic systems which provides a-priori bounds of solution branches. This is a joint work with T. Bartsch and N. Dancer.
