"Hidden" person three person game Markov: MA=MB={{0.1},{1,1}}: Fibonacci: game value =1 MC={{-2, -2, 0}, {1, 0, 1}, {0, 1, 1}}: game value=-2 A plays with C; B plays with C; but A has no direct contact with B . A, B are the "observed" games. Characteristic polynomial: 4 + 9 x - 3 x^2 - 12 x^3 + x^4 + 4 x^5 + x^6 - x^7. |

COMMENT
|
C is the "dark" or "hidden" player. it is simpler than a three three by three games, but the middle matrix was hard to find at gv=-2. Roots: aaa = Table[x /. NSolve[Det[M - x*IdentityMatrix[7]] == 0, x][[n]], {n, 1, 7}]; {-1.24279 - 1.07145 I, -1.24279 + 1.07145I, -0.618034, -0.618034, 1.48558, 1.61803, 1.61803} Ratio: a1 = Table[N[a[[n]]/a[[n - 1]]], {n, 7, 50}]; The ratio Alternates. Game value of total matrix is -1: Det[M]/(Sum[Sum[If[i == j, M[[i, j]], 0], {i, 1, 7}], {j, 1, 7}] - Sum[Sum[If[i == j, 0, M[[i, j]]], {i, 1, 7}], {j, 1, 7}])

M = {{0, 1, 0, 0, 0, 0, 0}, {1, 1, 0, 0, 0, 0, 0}, {0, 0, -2, -2, 0, 0, 0}, {0, 0, 1, 0, 1, 0, 0}, {0, 0, 0, 1, 1, 0, 0}, {0, 0, 0, 0, 0, 0, 1}, {0, 0, 0, 0, 0, 1, 1}}; v[1] = {0, 1, 0, 1, 0, 0, 1}; v[n]=M.v[n-1]; a(n) =Sum[v[n][[i],{i,1,7}]

EXAMPLE

mc = {{-2, -2, 0}, {1, 0, 1}, {0, 1, 1}};
Game Value mc=Det[mc]/(Sum[Sum[If[i == j, mc[[i, j]], 0], {i, 1, 3}], {j, 1, 3}] - Sum[Sum[If[i == j, 0, mc[[i, j]]], {i, 1, 3}], {j, 1, 3}])=-2
