Figure 4

The ( \(\pmb{h_{2}}\) , \(\pmb{h_{3}}\) ) parameter space when \(\pmb{m=0.001}\) , \(\pmb{\gamma=0}\) , \(\pmb{\gamma^{\prime}=1}\) , \(\pmb{c=0.6}\) , \(\pmb{s_{0}=0.1}\) , \(\pmb{s_{1}=0.9}\) , \(\pmb{s_{2}=0.9}\) , \(\pmb{s_{3}=0.8}\) , \(\pmb{f_{2}=10}\) , \(\pmb{f_{3}=30}\) . The symbols for the curves in this figure are as follows: (- -): \(A=0\) and \(\tilde{f}_{3}=f_{3}(1-c)\), (–): \(A=0\) and \(\tilde{f}_{3}=f_{2}(1-c)\), (-⋅): \(B=0\).
