Relation of fixed points and parameters for the system in all regimes. The regime represented by III i) with parameters regions σ (σ1, σ2) and μ ( 2 / ( 2 N - 1 + 2 N ( N - 1 ) ) , 1 ) has two imaginary fixed points. The red curve denoted by II) with parameters satisfying σ = σ 2 and μ ( 2 / ( 2 N - 1 + 2 N ( N - 1 ) ) ,1) has two equivalent fixed points. The three cases of II) occur in the intervals. The regimes denoted by I) with parameters satisfying σ (σ25) and μ ( 2 / ( 2 N - 1 + 2 N ( N - 1 ) ) , ( 2 N - 1 ) / 4 N ( N - 1 ) ) ; satisfying σ (σ2, σ5) and μ ((2N - 1)/4N(N - 1), 1); satisfying σ (σ 15) and μ (0,1/(2N - 1)); satisfying σ 1 5 ) and μ ( 1 / ( 2 N - 1 ) , 2 / ( 2 N - 1 + 2 N ( N - 1 ) ) ) have two real fixed points. The five cases of I) occur in the regions.
