“…According to the actual conditions, 0 and 1 are the only choices for the three parties' strategies, and at this time, eight equilibrium points can be found at (0,0,0), (0,0,1), (0,1,1), (0,1,0), (1,1,1), (1,0,1), (1,0,1), (1,0,0), and (1,1,0). According to Friedman's theorem, the Jacobi matrix is stable when all the eigenvalues are negative, and it is an unstable point if at least one positive real value appears [29]. The Jacobi matrices of the three-party game are as follows:…”
