Solving iterative equations. We set the parameter of the network to 2.8 and change the value of . (a) The intersection of a curve and a line stands for the critical threshold of the coupled system in the case of  = 1. (b) The intersection of a curve and a line describes the critical threshold of the coupled system obtained with  = 2.
